Randon Tech Exhaust???

[LPDesRoche]

I am about to purchase a cat back exhaust setup for my 98 GTS. I plan on going with a set of headers, high flow cats and either the Corsa's or the Random Tech exhaust. I heard the corsa kit in person and I really like the sound of it. But I have heard good things about the Random Tech. Looking for any info regarding interior resonance? I know the Corsa has none, any input on the random techs? Just trying to convince myself the Corsa is $500 better thats all.

I have had rt exhaust and cats for a year I really like the sound,drone isnt bad but I never had corsa so take it for what its worth.I will say I noticed no decrease in sill heat I did not measure with anything other than my hand, so not really scientific.
JonB set me up I would do it again but I would like a before and after temp reading just to know for sure.

Goldcup, the heat comment is interesting, I have a friend who has the RT Cats and you can put your hands right on the sills without being burned, I can not do that with stock cats.

LeeLand, thanks for bringing your car out to the cruise. I am thinking of buying the RT muffler back system and installing Dynomax 4"x20" round mufflers with the RT cats. I've heard sound clips of the Dynomax, and they had a nice deeper tone.

My 98 GTS had a stock headers, Roe sc, Roe Hi-flo cats and Random Tech exhaust. You could put your hands on the side sills no problem. The idle sound was tough, but quieted at cruise. Drone started somewhwere after 2200rpm, but with the Roe I never cruised over 1600rpm. WOT was not very loud compared to Corsa.

My 01 GTS is also Roe sc'd has headers, Corsa track w/o cats. It is LOUD. Idles loud and can be heard for a mile under throttle, but it does cruise quietly under 2,000rpm.

I have Random Tech cats and cat back. Love em both. Sound is awesome, no drone while cruising on the freeway, although you can hear a deep quiet rumble out back. I really like it, and wouldn't go with any other exhaust if I were to do it again, even if the Corsas were cheaper. JonB set me up.

Thanks for organizing the cruise. I am always up for a reason to ride around. As for the exhuast if you are going to do that just buy the whole random tech cat back instead of just the rear muffler section.

Are there 2 different styles of the Corsa exhaust? I know some guys say theirs is quieter than others. I know for a fact that the Corsa is loud under WOT? Some say theirs is not. Is there a track version and regular or something.

Belanger headers, RT cats and RT exhaust.

BTW My sills are probably 40% cooler after the switch

I have random tech hi flo cats and exhuast and B&B headers. the note is very nice. outside it is loud but not too loud. I do have drone though inside. as for heat my sills get very warm but won't burn unless you leave skin on there for a while. they have gotten very hot at the track though. i had racing tape melt to the sills. i won't do that again.

RT does sound nice, I will give them that. But like others have said, my sills got very hot! So hot my sills discolored from the heat.
I am sure they make a good product but to get them to warranty my cats was near impossible. In fact they didn't.

My Belanger/Random/Corsa setup sounds great. Loud and mean at WOT, nice idle, quiet enough cruising in 5th or 6th gear. Should have been my first mod.

[goldcup]

I might have to do some looking into my exhaust as after a long drive there is no touching of the sills or at least not laying your hands on them.

In the mean time you can try adding side sill vents. They cooled my sills down considerably even with an all stock exhaust.
