Default Custom exhaust and Borla muffler question??

A friend is getting a G2 Borla muffler for his S4. He said that I could have the old Borla muffler. It has a 3 inch pipe coming out of it and I was wondering how to install this on my avant.

Do you guys see any problem with running 2.5 inch custom pipes from the cat back and taking the mid-muffler (suit-case) out? Then running the 2.5 inch pipes to the Borla?

What do you think that would sound like, and would it produce a CEL or DTC?

Just pondering my options for a cheap custom exhaust.

Thanks,

Should be fine, no CEL or DTC as long as the o2 sensors are happy.

Default So, since I'm leaving the cat alone, no CELs or DTCs...

cool. I wonder what that setup would sound like? I don't want it to sound like a pulp-wood truck.

Default Exactly, cat-back you should have no worries....only what it will sound like :-)

It might be a little loud if you remove the resonator, you might consider putting in an aftermarket resonator along with the rear Borla muffler. Good luck
