Exhaust Questions

[95GreenGSX]

Im running the apexi downpipe. I know that it is a bit longer than other downpipes. I have a thermal r&d catback that I want to put on the car.

So my question is, how much do I need to cut off the thermal to make it fit with my downpipe?

I dont know if this will help you in any way, but the apexi downpipe is made to replace the cat. - making it longer then a downpipe which connects to the cat (obviously) if the exhaust system you have is made as a "cat-back" system they should match up from end to end. ( i dont know if the bolt flanges would line up though because of the two different brands ) -anyways good luck.

I think the apexi dp is actually longer than normal "cat delete" dp's. They do it that way so you can only use apexi catbacks.

true that, Shoulda went with Punishment Racings $125 3" DP, w/ T R&D exhaust like me. Couldn't be happier.

So your R&D fits the the PR dp? Does the PR downpipe delete the cat?

If it "needs" to be cut... best way to find out is by mocking it up ...

No sense in guessing around when you can find out exact measurements

Obvisouly, I wasn't just going to cut my exhaust because someone said so. I was going to measure it when I got it up in the air, but I just wanted to see if any of you guys knew.

correct me if im wrong but isn't the Thermal R&D made for FWD's only?
