272bhp NA and 325bhp on nitrous!! results are from a Maha dyno. Sure, once you got a decent size catback behind it. If going SC further down the line go with a 3" catback now. Even on a NA stock K20 3" catback has proven to give the best results
They're impressive results. Is there any system with a 3" bore? I'm going to use a spoon N1 and a 2.5" custom b pipe. Or do you think a full custom 3" system would be better?
