This is bone stock. I've already added the k&n filters. I'll be adding the 200-cel cats and custom made catback.
My local fabricator made the exhaust for me. The entire exhaust system will be vband so I can change things as I need too. I can easily put the stock muffler back on if this ends up being too loud. We don't have emissions or inspections here in Alabama, so noise is no factor.
FYI, my stock catback weighed 20.1lbs. My new catback weighs 3.7lbs.
If you truly have the stock ECU, you will absolutely want to at least update it to the "hi torque" (sport 350) version. It's just a safe software update, and it completely changes the feel of the car for the better!
Of course you could also go for the other chips that actually increase boost and HP, like the Sport 360 and the Red Race chip from "PUK": PUK Esprit Racing
I might do this eventually, along with the sport cats.
Let us know how you like the new cats. I'm interested in the added power and sound, but not sure if my neighbors will tolerate it!
