I'm pretty used to working with not too much space but you really don't need that much.
When you take off the stock downpipes, you can maneuver them out without letting the ground get in the way.

Not with the boost, but I have AtoFs and dyno plots.
I called my friend today to see if I could swing by to do a couple dyno runs but he didn't have time.
I guess I'll do it next weekend.

Just curious if you are running an exhaust system with the downpipes as well and which ones you picked if you are?
Thanks

I see that you have the secondary cats deleted. You're not getting in any check engine lights with the high flow catted dp's, correct? Any guess to emissions? bad smelling exhaust?

Good work.

I notice the factory dumps have a flexible coupling in them. It will be interesting to see how these and other aftermarket pipes go long term with regards to manifold stud breakages and such. Most stock inline twin turbo systems have flexible joints in them for a reason. If they didnt need to be there they'd save $5 a car anyday!
