ROCKETMAN Posted August 21, 2007 Share Posted August 21, 2007 Hi all, just returned to Supra ownership. I am after advice on the best method to reduce my noisy exhaust system (must be getting old!). Currently fitted is a full RSR exhaust system with double de-cats from Whifbitz. I am finding it just too intrusive. I am willing to sacrifice a bit of performance for a quieter system. Excuse my ignorance but not sure if the de-cats are more noisy or is it the RSR system, or both. Would it make any difference if I Dynamatted the interior? Many thanks.

Guest Chumpalot Posted August 21, 2007 Share Posted August 21, 2007 Dynamatting the whole interior could prove costly. The stuff isn't cheap! There's an alternative you can purchase from places like B&Q called 'Brown Bread'. It's essentially the same stuff just much much cheaper. Might be something to consider. I'd put one of the cats back in and see how it sounds then. Not sure what others might suggest. Link to comment Share on other sites More sharing options...

Thorin Posted August 21, 2007 Share Posted August 21, 2007 Put the baffle in. Link to comment Share on other sites More sharing options...
Max Headroom Posted August 21, 2007 Share Posted August 21, 2007 I used a thing called "fatmat" on the rear of the car, stripped out the rear seats and stripped out the boot. Made a significant change in damping down road noise and the RSR I had. If you have an NA an RSR and double decat is going to be freakin' loud even with the baffle in the RSR.

ROCKETMAN Posted August 21, 2007 Author Share Posted August 21, 2007 Na or TT? Sorry mate for not stating the obvious- TT! Thanks for that. Was'nt aware the exhaust had a baffle, will ask the last owner. Link to comment Share on other sites More sharing options...

Animal Posted August 21, 2007 Share Posted August 21, 2007 The baffle makes quite a big difference in the noise level. If you don't have one, that'd be the first thing to try. My N/A was undriveable with the baffle removed, the noise was so loud I had to wind the windows down at 60mph otherwise the noise just seemed to pressurise the inside of the car and make your ears bleed!

Nic Posted August 21, 2007 Share Posted August 21, 2007 You think the RSR is loud on a TT, on an NA they will make your ears bleed As said they come with a tail pipe silencer normally, although these tend to reduce the power a little. Other option is to get another silencer fitted on the mid pipe, this should reduce the sound a fair bit without effecting performance. Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 21, 2007 Share Posted August 21, 2007 Just buy a Tanabe Medallion Touring exhaust, they are very quiet, even with both cats out. Making a noisy exhaust is easy, making a quiet one with minimal back pressure is harder and more expensive, but the Tanabe one is excellent. You could fit a stock system, if cost is an issue, I have several mint ones. Tanabe Medallion Tourings I have fitted have come from MVP in the US, at a good price. maybe Nic in Hong Kong can also supply them, I am not sure. My customers have arranged their purchase themselves, and had them shipped to me direct. Link to comment Share on other sites More sharing options...
ROCKETMAN Posted August 21, 2007 Author Share Posted August 21, 2007 Thanks for the advice. Paul at Whifbitz has recommended an HKS silent Hi power. Just wondering if my RSR exhaust would sell no problem to help fund new exhaust. Start of the Supra spending spree, and I've only owned it 24 hrs!!

Don't think you'll have any problem selling the RSR mate, I love mine, then again I am a loud b*stard anyway Link to comment Share on other sites More sharing options...
hadyn Posted August 21, 2007 Share Posted August 21, 2007 How about say putting the 2nd cat back in? That may reduce noise a bit Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 21, 2007 Share Posted August 21, 2007 The Tanabe is FAR FAR quieter than a Silent Hi power, totally different kettle of fish. Link to comment Share on other sites More sharing options...
ROCKETMAN Posted August 21, 2007 Author Share Posted August 21, 2007 Going to try fitting the 2nd cat if I can get a hold of it. Love the look of the RSR I must admit. Anyone reading this knows where I can source a TANABE mentioned by Chris, please let me know!? Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 21, 2007 Share Posted August 21, 2007 How can someone love the look of an exhaust, it's just a pipe sticking out the arse end of the car.... ? The Tanabe systems I have fitted came from MVP in the USA, I guess there aren't any UK stockists? Link to comment Share on other sites More sharing options...
Guigsy Posted August 21, 2007 Share Posted August 21, 2007 anyone got any recomendations where i can get a baffle for mine? Prob is its a custom exhaust. makes an ace sound. but anything longer than 30 mins driving you you develop a headache. Have tried envy but because its a custom exhaust they said they couldnt realy do anything. Anyone know who might make them? there is a place near me that does custom exhausts but havent been in there yet. Would be gratefull if someone could help me out Link to comment Share on other sites More sharing options...

True, I'm just a bit of a perfectionist. Why have an immaculate car which is your pride and joy with a piece of rusty old shite poking out the rear. Maybe my attention to detail is OTT...

b_have Posted August 21, 2007 Share Posted August 21, 2007 Problem with the normal "baffles" is that they are very restrictive. Spend a grand on a 4" Ti exhaust and stick a 30mm peashooter in it? Joke. I made a removable silencer from perforated 60mm tube, had some end plates spun and stuffed with fiberglass wadding ala motocross cans. Took 9DB off my HKS pipe with little restriction.
