No Cat Back, Still Good Performance?
Ok, I was supposed to buy a guy's slightly used N1 single cat-back, but he has never responded to my picture requests, sooooo....Will I see any substantial hp gains running the RB header and presilencer w/o an aftermarket cat back? I will get a new N1 here in a month or so when I can afford it, but in the interem, will this setup be good? 1991 n/a....

guess it depends on the condition of the stock mufflers but ya, it should give pretty good improvement in power.

you are gonna put a cat-back in a month anyways so install what you have now !!

you will gain a little bit of HP with an aftermarket cat-back.

Just wondering what to expect. I know the biggest exhaust performance gains comes from the header and presilencer, but I was just wondering! Thanks guys!!

leave the entire catback system off and I guarantee you'll see a performance gain Might be a bit loud though!
