Re: Stainless exhaust pipe diameter on JTD, what size should I pick?!
About Mark_JTD question of performance improvement...
Several Alfa 147 1.9 JTD 8v of my friends are remaped, and only my Alfa had mentioned modifications (de-cat, BMC-CDA, etc.). All agree that my Alfa run better than others, especially in low RPM (under 2500). Turbo lag is significantly smaller. I assume that this was due to additional modification. I am forgot to mention block of EGR valve and replacement the overboost valve (i.e. solenoid valve), according to recommendation from our friend kgb.
I hope that this help in your tuning activities and good luck. Dusan.
