Alright my n/a has a rb header to 2.25 inch trackpipe to 2.25" cat-less back exhaust that flows as straight as possible through the drivers side exit.... I was thinking about swapping the cat back over to my t2.... here's my question... on stock everything... will the cat-back create enough flow to have to worry about the boost getting too high... my t2 is bone stock... and I don't feel like porting the waste gate right now... and I'm waiting on injectors and a standalone untill spring. think she'll be fine with just the cat back? it's only 2.25" single pipe... so I doubt it flows much more over stock... I've tried searching and I get all kinds of cat back answers but none on bone stock cars.

is this a dual or single cat back???

single catback... 2.25" ... straight through muffler exits on drivers side... very minimal bends.
