Hey guys. I have a b18c with a ported gsr head, stage 2 skunk cams, 11.8 compression, skunk intake, stock throttle body, rage big tube header, high flow cat and an RSR exhaust right now. Any opinions on the best cat back exhaust for this setup. It made 198 hp with no exhaust, but obviously can't have a daily driver with open header. Not sure what to get, but the RSR is a definite bottleneck now. Thanks for the help!!

 

2.5" Kteller with magnaflow works.

 

At least 2.5" piping, I usually do 3" on higher powered NA cars. Check out ASP for their piping kits in 3" and then get a magnaflow muffler and possibly a resonator if you want it to be quiet.

 

Look at the Skunk 70mm or 76mm exhaust systems, no welding required.

 

ya i got the regular one now think its like a 62mm or somthing but it sounds nice and deep tone .. but sometimes kinda loud in cabin around 2600 3500 rpm but if i ever go 3inch i would probly buy another skunk2
