Do you have any clearance issues? If so, what's your setup? If not, what's your setup?

If I go with the Invidia O2 housing (2.9" outlet), I'd have to go 3" the rest of the way, right? I'm thinking of going with a 3" resonated test pipe (probably MR), and then the Road Race stealth catback, which is 3".

I'm not sure which 3" downpipe to get so I won't have clearance issues. Do you guys have any suggestions?

Lastly, are there any 2.75" resonated test pipes? I haven't been able to find any.

TIA

 

If your going with a 2.75" dp get a 3" testpipe......

 

Thanks. I don't really want to go 3", but if the O2 housing is 2.9" and the only resonated test pipes are 3", I think that I have to.

If I could find a 2.75" resonated test pipe, I'd go with the MR O2 housing and the Espelier downpipe, but I can't find a 2.75" resonated test pipe.

 

My buddy is running the Invidia O2, Invidia N1 catback, invidia downpipe, test pipe. No fitment issues but a minor clearance issue with the 3 " downpipe. It can be fixed w/ washers or minor bending of metal.

 

That's what I was afraid of. Thanks for sharing and saving me the headaches.

 

I am running a 3" DC downpipe with no issues on my EVO 9 MR. It clears just fine.

 

I have the invidia o2 housing and full 3" turbo back exhaust from perrin, the only fitment problem was fitting the 02 housing to the turbo side, the holes dont match up for anything. but other than that it works fine and gave a little more power.

 

Thanks guys. I'm gonna go with the MR O2 housing. It's 2.5", not 2.3" as advertised on Lancershop, so it's not as bad. Mated with a 2.75" downpipe, it should help me get some more bottom end torque. 3" after that. Rally cat (well, gotta find out how much that costs first) and RRE stealth catback.

 

How did you remedy this?

 

drill? dremel?
