Hey I was wondering if you had a downpipe on your T2 before the motor went out. If so, did it bolt right onto your Garret turbo? My friend says the RB Turbo-back exhaust system will only bolt to a stock turbo, but since my stock downpipe connects to it, shouldn't the RB system bolt to it?

Yes, it will fit. The Garrett turbo is an upgraded TII turbo.

You should send him a PM instead of asking him a question on the forum.

yeah it bolts right up

Ok I'll remember next time 13BAce. Thanks

if you ever get to the track you should be able to run high 13's

Thanks, I'm working on it. For some reason though, I'm only boosting a solid 5 psi. I'm thinking my downpipe and main cat is just really clogged. I'm pretty sure I don't have a boost leak. Could a clogged cat and dp lower my boost by that much? Anything else cause my boost to be so low?

A clogged cat will account for a pretty good loss in boost levels...if you get a bigger DP and hiflow cat, you should be back up to 10psi provided you've got a catback as well.



Also, your intake filter can hurt your boost some too...if you have a stock intake setup or a really dirty filter, the flow can restrict your boost levels...by adding a larger 3" TID you can also increase your boost levels...

i'm gonna say cat's are clogged before when my car was stock was hitting about half on the guage which is 5-6 psi. wait till you get around 11psi it feels like a new car
