GavinsBeard Posted January 14, 2015 Share Posted January 14, 2015 Would a straight pipe with no silencers and just a back box be a good way to go for my N/A EP91? Just wondering because i have a hole in my cat and i'm not sure if it's making me loose back pressure or power or something and would a straight pipe gain/loose power? (Trying to squeeze the most out of the 4EFE lol) Quote Link to post Share on other sites

daniel_g Posted January 14, 2015 Share Posted January 14, 2015 You need back pressure in a N/a so having a straight pipe isnt gonna be great for performance.Personally id go with a 2" system with a small mid box and a decent backbox Quote Link to post Share on other sites

daniel_g Posted January 14, 2015 Share Posted January 14, 2015 The front section of the Japspeed would need modded to fit on a N/a, rest should be ok, but those systems are far too large in diameter for a N/a especially if you are after performance. Quote Link to post Share on other sites

Think if i just got a back box it'd be worth de-catting my N/A? cats already got a hole in it... Quote Link to post Share on other sites
RustyEp91 Posted January 14, 2015 Share Posted January 14, 2015 I have a straight through to back box system its a 2.5" system made by a custom garage. Started as a cat back then hadthe cat took out no real huge power gains little quicker acceleration but a raspier exhaust note. Quote Link to post Share on other sites
