what exhaust setups are you running? im interested in finding out the exact gains from losing the stock H pipe. anyone have a stock H and an aftermarket? i need a stock H for my project.

 

SLP's new setups are probably the best on the market right now, they are for F-bodies, so it should be the same for stangs. sounds great too.

 

 

Myself as well as a few friends of mine run Magnaflow X pipe/catback.

Im sure SLP's stuff is nice but I doubt it is worth the extra $$.
Just get a nice stainless steel system, the gains will be about the same regardless of which system you choose.

 

SLP is very expensive. a nice set of MAC or BBK headers with X/H pipe and magnaflow MAC, or Dynomax mufflers would be cheaper and work very well.
