You should have heard my car with a PT-61 turbo and straight through 3" exhaust. You literally could not hear anything else if you WOT and forget talking on the phone.

When I had just the RB true duals header and presilencer, nothing else after the presilencer. Had to drive like this for a month, and damn thing was loud and annoying. Wakes me up though while driving 7 in the morning lol and my neighbors.

My first ever true dual setup
RB true dual headers to a pair of Dynomax ultra flo, that **** was loud without a presilencer. Month later bought a RB presilencer and installer it.

Gotta love the true dual exhaust pulses

I have good responses from people in person....my particular favorite was "Every ******* small car should sound just like that!".

I am liking it.

RB street header, RB pre silencer, ebay 3" catback

[youtube]http://www.youtube.com/watch?v=0umjWRldQH4[/youtube]

this car is also S5 streetported and carbd, turbo inserts.

Just tried my friends exhaust on, it was waaaay too loud.

I'm curious to put it back on now for a race event because I got rid of the presilencer and run RB street duals (not true duals) a 2.5" test pipe 304 stainless to the RB street header.

They are technically "glasspacks" but they are stainless steel packed, no fiberglass and are perforated core, so little to no restriction. You might want to get the longer ones though, I guess that depends on how loud you want it to be.

Damn, long time no post.

I just crammed a presilencer in the cat "delete" pipe to get rid of the chain saw noise. I just recently threw the cat back on because I am coming up for smog inspection, so I don't have a video yet.

Once I have a video of the now silenced cat delete pipe, I'll post back up.

I still haven't got her inspected yet, but once I get the smog done and the new silencer on, I'll post a video of non-loaded revving, and another of actual driving.

It always sounds different when the engine is loaded.
