Not much at all. Maybe 1 - 2 rwhp, if that.

About 20hp worth of sound, but about realistically 1-2hp.

Not much, i barely noticed anything when i did my flowmasters, and i did an entire cat-back replacing all the small exhaust piping.

Sounds like a 30HP gain though

I didnt feel any gain when changing to the American Thundercatback, does sound much better though, like most people said maybe 1-2 rwhp.

weld-in flows won't get u much at all. changing the stock piping with straighter pipes should increase a little bit of horsepower, though not much.
