Spyder 2g Spyder GS cat-back

[vteclipsegs]

I was looking at purchasing the cat-back system from thermal R&D. I had a couple questions and after some research most got cleared up, however a few remain. Will a 420 cat-back fit on my n/a spyder (seems like people are 50/50 on this). And secondly will an exhaust larger than 2.5" in diameter really cause me to lose bottom end torque (the only saving grace of a n/a 2.4)?


this is the system I was considering.

From the cat back, a 420a exhaust is identical to any other FWD DSM exhaust. It will fit.

Larger exhaust will cause you to lose a bit of low end torque, due to the loss of low end cylinder scavenging. This is minor, though - I can't imagine you'd mind it much.
