I have a Skunk2 muffler and vibrant high flow cat, both 2 and a 1/4inch not yet installed and I'm now thinking of getting the RSM supercharger. the est. specs are 60hp gain at 6PSI and I was just wondering if I need to or should up size the exhaust to 2 and a 1/2inch piping?
I have one true love in my life...And my girlfriend sits next to me in it
2.5 would be best with the s/c
2.5 is good to go.
pacesetter 4-1 is perfect for the job.
