Any recommendations for a turbo back system for this.

Must be stainless, and not mild steel.

 

Just fitted a Janspeed downpipe with Hks Hyper to my Sti8 sounds very nice and you dont need to ask about the quality.

 

agree on the hiper, I ve got one (loud but it is mild steel centre)
buddy club if you want the best but you will pay (v v loud)
Blitz if you want loud (v loud)
scoobysport\tsl group n\haywood and scott (loud)

 

I'm asking for a friend who doesn't have a pc.

He had the Blitz NUR Spec on his last scoob, but thought it was too loud () and didn't like the bung idea - Weirdo!!!!!

He is very fussy and it must be made completely of s/steel, so that rules out the HKS (even though they're are nice).

Thanks for your opinions

 

Im getting an 02 STi prodrive on saturday, im trading a 2001 wrx with a full scoobysport decat, which im taking off, BUT i've mailed scoobysport yesturday and they advised not to mess with the exhaust because it will be set up by prodrive.
I would seek advise before you change the exhaust.
Also would like to here from you if you get any joy in which one to fit.
Thanks ByByR1

 

By most accounts, at normal power levels (as in <350-400bhp), the STi PPP exhaust is pretty unrestrictive, and I expect you'd get fairly minimal power gains changing it. If it's noise you're (or your friend) after, just change the backbox IMHO. If it's power you're after, look at other supporting mods (intercooler, induction, new turbo) or an ECUTEK remap, which will apparently yield pretty good results with the standard PPP exhaust. Also, if you've paid for PPP, seems a shame to kill the warranty at the moment. All IMHO, of course.
