a three inch is much better but space may play and issue fitting it under the car maybe with a body lift it would fit better

Jake,
Definitely go the 3", It will let it flow just that little bit better. I don't know if cost is going to be a factor but there won't be much of a flow difference if you just go press bent exhaust. Take it to a truck exhaust place, they tend to do a better job on the bigger exhausts.
Cheers
Paul

Is the turbo coming as part of a kit? Denco supply aftermarket turbo kits complete with mandrel bent exhausts!

I got a kit for a 2h with a schwitzer turbo and the exhaust is mandrel bent to the rear side of the muffler (which is straight through) and pressed for the last 2-3 feet. 3 inch exhaust would be good though.

Dont get to flash (read expensive)
no need for mandril bends
2.5 inch short as possible with a hot dog (just so it looks like it has an exhaust)
does the job fine on my 3bt

I think they say the exhaust only needs to be as big as the dump pipe from the turbo...

Go the 3". Had a 3" on my old turboed 2.8 Lux. Went well and whisled its head off down low, at first ran with no muffler at all, but the bark under power got anoying so put a straight thru on it and got rid of the annoying bark. Blew my mates 2.8 turbo away but i had some head maching done and also got it match ported. seemed to work well.

check out the 'FLOWMASTER' web site, then call barnes auto's in Nambour and get one
they are the best !
everything else is just a compromise
