I have already done the search on exhausts and catback systems. However, I did not find an answer to my question, which is what exhaust sytem gives the most hp. Keeping in mind, that I don't care about price or the noise level as long as it is street legal. Please I'm not looking for opinions on the best sounding or looking exhaust just what gives the most hp. If anyone has any factual info it would be greatly appreciated. Thanks

 

run just a 4" down pipe, mid-pipe, and straight pipe out the back.

 

well, if it's too loud it's not street legal. depends on where you live.

 

i agree with the straight pipe, no restriction = best flow its loud but hell its what i run,

 

You should check with your local county to find out what is legal (especially noise wise).

It would be a shame to spend a lot of money on an exhaust that is going to get you a ticket every time you are on the road.

 

hmmm good point .... get a resonated midpipe, should quiet things down a tid bit, but i dont get tickets, and i was runnin a straight downpipe for awhile , but for some reason i got like 3 tickets when i did have exhaust

 

I don't really think there is much difference between exhausts. I mean, there may be 1-5hp differences from the major manufactur's, but you really shouldn't stress over it.

 

easy for you to say, 5 hp is .9 percent for you, for me it's 2 percent
