I am running an ABA manifold/downpipe with 2" straight back :/
doing some tuning today and hopefully get it sorted out. It feels way too weak to be making so much heat! I would have never guessed!
How did you solve EGT trouble? Did you change back to stock?
I am planing on buying such manifold because it should fit nicer than stock TD one, but if you had increased EGT's with it I 'll buy some other...
