Hi! Im a Newbie on this site!!

I have a couple of questions regarding performance upgrades on my stock Maxima 96 with 100000 miles and still running very strong.

How much HP gain is expected if I change the exhaust components and what are the components?

How much HP gain if I install a High flow intake??

Thanks in advance for any inputs

 

The best thing you could do in my opinion is a y-pipe....as for brand of y-pipe it's up 2 u.....same for intakes there's place racing cai and jwt/stillen intakes also ther is a ram air thing you could do at home for like 2-5 bux.......do a serch and you'll find more about ram air intakes and the stuff u axed about......
