If I am going to replace my stock downpipe with a 3incher are there any special modifications that I am going to need to make to any part of the exhaust system or engine? Or are there any tricks that I can do to really help maximize this upgrade.
I replaced my stock downpipe with a Terry Houston
3" downpipe and the only things that I had to do was to cut out a small piece of the Turbo Shield (for clearance) and switch to a 3" Cat.
