Should I cut/weld the transition out of the HKS to make a full turbo back 3in exhuast (loud and requires hacking my $$$ exhaust). Or keep the 2.25in stock DP with the T28 and sell the Apex DP? Is it worth it to port the T28 if I keep the stock DP? And is it necessary to port exhaust manifold to match ported T28?
Sorry for the newb questions...but hey, thats what this forum is all about right?  |
I'm running a 16g to completely stock exhaust, it still spools relatively quickly and blows away my t25 even with minimal fuel mods and low boost. Even worse than just the stock exhaust I had my o2 housing ported knowing full well that it would hinder performance until I picked up a larger exhaust. Running the stock downpipe for the time being shouldn't be an issue until you can sell your apex downpipe and get an hks one or get a shop to put something together.
