exhaust for twin turbo legacy

[2ndlegacy86]

Hi guys. Got a quick question.

Im looking at getting a new exhaust for my 2001 twin turbo legacy (revd), trying to decide if i should go turbo back or just cat back. Ive read up that turbo back can cause primary turbo to overspool(?) Just wanting to know if anyone has any info on which path i should take lol

Thanks in advance

Catback if you're more interested in noise or turboback if you want some real performance gains. It'll overspool without a tune, but being a Rev D they are tunable. A good tune will give way better performance with a smaller VOD and better economy. Think Marky on here could do you a tune for one. He was advertising on TM for a while but not sure if he still is

Awesome thanks mate. Thats what i thought too. Is there any gains from a cat back?

So how about Rev A-C? The Rev A-C ecus aren't tuneable so does that make getting a turbo back exhaust a waste of time or worse- dangerous to the turbos?

Just need some form of aftermarket boost control, MBC/EBC.
