I have the full header back, way too loud. I am having the RP Supercat I had on with the oem cat back modified to fit the 3" TurboXS cat back. Was looking for sound clips or any idea how much quieter this will be. I can add a resonator when they mod the Supercat but I don't want it too quiet, hoping just the Supercat will be about 50% as loud as the race pipe. I have heard from one of the local 8 guys that it should be bearable once the Supercat goes on. Anyone with experience?

 

you need to find a local guy who has the setup you want cuz a sound clip just wont quite cut it....

 

The RP Supercat should bolt right up to the turboXS catback. The RP supercat is designed to fit a stock style header and a stock style catback. The turboXS catback is designed to fit a stock style mid-pipe/cat and the turboxs race pipe. Its only the turboXS race pipe that wont install to anything but a turboXS catback.

If the rp cat does not quiet it down enough you can just have the cat conv cut out of the RP supercat and installed onto your race pipe which has already has a resonator.

 

I can tell you from experience, the TurboXS catback will not bolt to the RP Supercat or to the stock midpipe, we had 5 people looking at how to do it and they all work on RX8s at this shop all the time. The racepipe does not have a resonator, its a straight pipe. I'll be adding a resonator to the RP, still too loud for me.
