turboxs 4" bellmouth... as part of their stealthback.

As far as fitment goes, its ok at best... you have to move the ac drain line, hack the hell out of the heatshield, and I have a small exhaust leak at the dp to cat joint because the dp sat about 1.5" below the cat before bolting everything up, it also sits a little low at the cat because of this...

Its fits fine with some minor adjustments. it bolts up to the fpgreen just fine, the only problem will probally have to matting it to the catback,but with right exhaust gasket and some copper spray your fine.

i wonder if it 3in, or say they say it is.

Noob alert...

Are we better off with the catted version to prevent boost creep?

I will be running an AP @ stage 2 and I've been trying to find a solution for the boost creep issue on the 2.5L. I found that it is best prevented with either a catted DP or a more restrictive cat-back (or axle-back)

I have an Espelir 3" catback so I was going to buy a catted DP to avoid any problems....am I right or am I missing something?

going catted MAY help with boost creep, but it doesn't always prevent it. i had a cobb catted dp running stg2, i still get creep =\
