how much of a difference does a pipe make on 250sx?

Just wondering if there was any substantial differences between a stock and an aftermarket cobra exhaust for a 85 250sx?

i have a cobra system on my sx. there is a noticable differnce in performace thats apparent in low end power, however it's" LOUD":thumbsup:.. if you have a neighbor thats close by,they'll be whining about the noise..:headbang:
