Exhaust Question. I tried thread searches and i cannot find a define answer. Bottom line is I HAVE BBK 1 7/8 headers with 2.5 ORY on the way. I currently have An All Stock a4 Z28.
Should I keep the 2.5 ORY And Get my SLPLM?
Or
Sell the ORY And run A custom True Dual Exhaust?
If i run true duals, what size piping should i go with? 2.5? 2.75? 3? 1.5? Lol
I'm Going for the most performance on a factory motor with a lid. Maybe heads and cam later.
I don't really care about drone or how loud itll be. I just want the best numbers dyno wise.
