Now tell me, guys, where is your 300+rwhp that requires an aftermarket exhaust? Does anybody in this thread actually own a turbo engine producing over 300 horsepower that necessitates the noisy exhaust system?

Lmao I have a 300 HP capable motor; though I run a moderate, daily boost of 6 psi. My cat is gutted, but I'm running a lowkey muffler on my 3 inch straight pipe. It sounds quieter than a KA that's for sure under low RPM's but some people daily their 240's and I'm sure they're trying to make their 240 more luxurious to either themselves or the people they might drive.

I want to see in a actual comparison test against dynamat. I've heard nothing but good things aside there price but it might be worth the extra bucks if it actually works better.

[rwtf]

I just got me a free sample!!! wewt.

Compared to before it is a night and day difference. My exhaust noise was cut down by 60-70%. I am 100% satisfied with their product and if you are in the market these are the people to call. +1 for a legit company with a legit product

Thanks for the kind words LA! If anyone else is interested in our product, call now for your free sample: 1-855-GTSOUND.

Screw that noise. Go to Home Depot - $8 a roll.





Work's great, did it to my 350Z when I installed the sound system. All that "tinny"-ness was gone, sounded like a German car after that.. Door thunk and all.

350z's aren't that old so they don't have as much road noise as an S-chassis either way
I ordered a 10ft sample and I'm excited.

FREE 10ftsq > $8 roll

[zerodameaon]

I have been thinking more and more about putting in sound mat in my car but I think the only way I could benefit is if I just stuck it to my ears every time. Damn convertibles.

OP thanks for the heads up on this deal.

+1 There must be a reason why dynamat has been the leading the industry is sound deadening all these years. The phrase often imitated never duplicated comes to mind. But hey, prove me wrong and ill be a believer.

[Sauce98]

Just what I need, this is awesome. I'm calling tomorrow. Thanks OP

[mrizsuki]

lol, any type of sound deadening will REDUCE tons of noise in any car, especially our s-chassis. for the weight part, anyone who carries a tool box will already add easy 20LBS-40LBS to their car + golf clubs. so weight is not an issue. +1 for peaceful luxury silence

[Kevin_S14]

do you know if they still offer the free 10sq ft? im kinda interested in this

dang dude, it's just sound deadening lol.


Why pay $8 bucks now when you can get some stuff for free? Why not take advantage of it?

We always welcome comparison of our GTMAT product to premium products like Dynamat Xtreme and Damplifier Pro. While we market our product as a discount product with published differences, we do understand there will be feature by feature direct comparisons. As you know the higher end products use Butyl and we have and asphalt based product. Butyl has a different smell and has different heat-related properties than asphalt based mats. Lets be perfectly clear: GTMAT is not claiming to be better than Damplifier or Dynamat Extreme. If you can afford to do your job with Damplifier or Dynamat Extreme, you should as its features are the best you can hope for in a sheet product. But if you need a discount alternative, GTMAT is worth a look. For the price, GTMAT gets the basic job done, almost as well as the high-dollar premium products, and much better than the 'garbage' at the hardware store.

That being said, our free sample is 100% completely free, we pick up the shipping charge as well. So why not give us a test drive?

Now tell me, guys, where is your 300+rwhp that requires an aftermarket exhaust? Does anybody in this thread actually own a turbo engine producing over 300 horsepower that necessitates the noisy exhaust system?

To answer your second question: Yes I own a turbo engine (sr20det) producing over 300 horsepower that necessitates a noisy exhaust system.

And to answer your first question: My 300+rwhp which performs extremely will with my 3" aftermarket exhaust is in the driveway.

Any other questions?

[kojiki88]

Just called in for the free sample, I should get it in 3 to 5 business days. I have never tried the other products but I will give a review on GTMAT once I put it in my S13. I'm not worried on the weight added with this since I am pushing 300 RWHP (Oh, I also have a 3" turbo back exhaust. Even though its not unbearable, anything that helps quite down the cabin its a win win situation.) Thanks GTMAT for the Free sample!!

Read first! I said they don't have as much road noise. 240's have much more than speaker rattling

^ +1 You got it. Why not take advantage of it while it last free is always good

[240SilviaX]

GTMAT is the shit, They ship fast, i covered everything from the hatch to the rear of the front seats

[DreamN]

I've always wondered how products like these are suppose to be used. I've seen install photos of people covering damn near the whole car in the stuff and some who do selective strips? Which is it? If the latter, then how do you go about selecting the actual areas to be covered in the stuff?

[nismostormtrooper]

GTmat is pretty legit, used it to get rid of the rattle from the rear deck. Worked perfect!

I'll tell you why, sir/ma'am- Because the good stuff doesn't have asphalt in it for a reason...

Totally LOL'd when I read your Rico Suave way of saying your product "has different heat-related properties..." Translation: It sucks in the heat! You can't use asphalt-based products near anywhere that has the potential to get hot (firewalls, over exhaust areas, CA, AZ, TX or anywehere else that has hot summers)... Unless you like a mess in the driver's compartment and the inside of it smelling like a freshly paved road... The reason? Physics- Asphalt becomes pliable and melts when even mildly heated- much like how the road gets squishy when it gets hot.

The good stuff on the other hand, not only deadens sound and reduces rattles wonderfully; it also "can withstand temperatures of -30 to 400F" (Source: Summit Racing® Ultra Heat and Sound-Deadening Mats SUM-879006 - SummitRacing.com ... which is what I used). Not all of it is as expensive as Dynamat; but if you want quality, there is still a price to be paid for it.

In otherwords, if you are an S-chassis owner who has already polluted your car with knockoff "discount mods" because you are on a budget; this "discount alternative" may suit you nicely. However, with your best interests in mind; I strongly urge you to reconsider this one- There are just some things you shouldn't skimp on.

BTW Props to the dude who used the $8 Peel & Seal. Not my first choice, but I bet it will succeed where GTMat will not.

[240SilviaX]

LoL @ Mikester ,, my car is black and has been sitting in the direct sun every day and my car gets hot like 140* inside since we have been getting these recent heat waves in CA. GTmat is rated up to -100*F to 300*F and had not melted away untill 375F* in tests.. so lets average 50*F from your Summit racing stuff that you paid $100 more than I did for the same amount of material... Not once has my car started to smell like asphalt or has it started to melt away. But its nice to hear your assumptions, the Peel and seal type from the hardware store will melt away way b4 the GTmat will they have tested it and made a video of it. And discount budget haha, Why pay more for sound deaden-er when I can spend that money on my Powered By Max parts .. just looks like another person likes to talk shit and has no idea what he is talking about.

[240SilviaX]

And no where in the summit page it says what its made of, so all n all you have no idea if its a asphalt or not. just sayin..

[dizzariot]

Awww you guys

If you have 'real' wheels: use Dynamat.

If you have fake wheels: use GTMat.

Maybe now you can stop bumping your peepees together now.

Actually, I did extensive research knowing that whatever I put in was going to be a permanent fixture... This is what Summit carries under their house brand: Frequently Asked Question About Hushmat

^^ Clue in to the part where it says "Why doesn't HushMat offer an asphalt or PVC damper like the “other” guys?"

Have a great day.

[240SilviaX]

LMFAO hahaha hurt feelings report how cute you posted than instead of responding on my facts that makes your "translation" bullshit. It does everything its designed to do well. Far from hurt feelings. I had a great day got alot of stuff done to the car, thanks for letting me know you care .. who cares lol, it does its job doesn't melt or smell so who gives a fuck. and I saved $100

I have been a high-end car audio dealer/installer for 20 years now, have personally done installs on over 25,000 vehicles and I'm a Second Skin dealer to-boot... and that post I just quoted is the most honest reply I have ever heard from a product rep/manufacturer. Most reps just say their product is the best you can buy and talk it up like they are re-inventing the wheel... I get sick of it.

Kudos to you man... I may just have to try your product out as a cheaper price point product.

[Corbic]

Well I just placed an order. Well see how this does on the my S13 when it gets here.

I currently have all poly bushings, solid subframe mounts, welded diff, SR, 3" straight exhaust to a Mag. Muffler a FMIC with no BOV and mechanical fan.

Unlike my Tacoma, there is no confusion if the engine is running!

Another product out there is Fatmat, I may try some of there's as well, although ion not sure how to do a comparison without striping out and changing over the products.

You are more than welcome to state your opinions but I would advise people to take your information with a grain of salt as you have not even attempted to test our product yourself. GTMat is located in Texas and the majority of installations have been in Texas where, as you know, summers can hit up to 115 degrees. We have several employee vehicles that were covered in GTMat during the summer and have not had any type of melting issues. We have also shipped samples to California and Arizona in the summer and have not had any reports of melting from these customers. As far as an asphalt smell, our product has been engineered to have very little to no smell. Most of the free sample users who reported a smell, noted that it was hardly noticeable and dissipated after a few hours of installation.

Take a look at our test video and feel free to call me when you are ready to give us an honest review.
And by the way, it's ma'am and I will be installing GTMat on my 370Z doors this week. I'd be happy to take a video for you showing the temperature here and what not if you wish.

You are more than welcome to request a free sample and let us know your thoughts. Give me a call if you want one. I'd like to state the we are not out to deceive customers about our product. We know there are better options but they may not work with a budget that has been set.

[GTMat]

For anyone still interested in the free sample, we will be accepting orders today until 5PM central time. Let me know if you have any other questions.
