R33 Exhaust On A C34?

[boost_bus180]

hey guys,

just a quick noob question... looking to replace the catback on my stagea and was wondering whether or not an r33 exhaust is the same?

thanks

I had a 33 front pipe on my S1 but the rest is different. Have you got a stock set up or are you going to 80mm or bigger? I don't have a cat but you could just measure the pipe before and after the cat if you are buying a new one.

Sorry - see you are talking cat-back. Pretty sure you need a Stagea specific one or you could just get an exhaust shop to make one up.

yeah Ive currently got a 3 inch system from front to back but have a couple of holes in the mid and rear mufflers so rather than repairing them I thought replacing it with an r33 catback which are a dime a dozen would be a quick fix.

it will fit, but you need a section put in after the centre muffler, and possibly a section added after the rear diff. It will probably still be cheaper getting one modified than getting a zorst shop to make it all custom.

I've got a 33 cat back on my S2. It has had a piece probably about 10inches long added in the middle and the back box tweaked around slightly as well as the hangers moved.

Has anyone fitted an R34 sedan exhaust?

I hear the r34 ones fit better

Call a tuning house that KNOWS stageas (c-red in perth for example)

they'll tell you exactly, I remember asking once but a bit fuzzy on the details

I was in at an axhaust shop today and the guy told me that the X-force R33 systems require the rear hanger to be moved 8" to fit into a Stagea. He said they were a perfect fit.

I'm not convinced as the Stagea has a longer rear overhang than an R33.

+1 The 3" system on my Stagea was originally for an R33. Just added a longer section in the middle, via a Berklee resonator, and all was sweet.

A skyline exhaust WILL NOT be a direct fit for a C34. You need to add some piping, generally some before the resonator and some after it. A descent exhaust shop will be able to do this for you rather cheap. So IMO if your after a cheap turbo back for your stag buy a 2nd hand RB25 3" bellmouth front dump for about $100 and then wait for a catback comes up that you like. Shouldn't cost any more than $100 to mod and fit the cat back, do the dump yourself.

Heres the comparison of a stock rs4v zhorts with a R32 3 1/4" cat back

Clearly its not going to fit but hook it up and have a listen to see if you want anything of it changed while your getting piping added.
