What exhaust pieces do Prodrive fit as part of there PPP.?

Ive got the Prodrive backbox but wondered what other sections I should fit as I dont want it to loud but do want to engine to breath better (the backbox sounds ok)

Would I see any BHP gains?

It has to be prodrive as i want to keep my warrenty.

Is there four sections to a newage exhaust?

swifty.....!

on the sti they fit down pipe sports cat, decat cat pipe and back box and keep original sti centre secion.

but you'd probably still void warranty if exhaust parts are by prodrive as the only reason you don't when you have ppp fitted is its done with prodrive remap etc by a prodrive dealer so has all of the correct bits. so if you want to do this on your car ask your subaru dealer first as some will say its fine and some will say it will effect waranty as it changes the set up.

but you could always keep original exhaust then should anything go wrong you can put it back before taking car to the dealers.

power wise on new age you get best results with remap as well to get the full benefit.
