ok, Ive got a RB turbo back exhaust and i wanted to get a midpipe for it. Im wondering where the rest of you guys got your mid pipes and how to go from a 3" DP to a 2.5"(???) catback. Any pointers?

Troy

 

Banzaitoyota has one for like $30 I believe.

Unreal deal.

nm, it's for S4 Na's only

 

doh, lol anyone else?

 

just go to an exhaust shop and they could make you one pretty cheep

 

nope, midas wouldnt do it, even for a "race only" vehicle. not only that, I currently dont have a cat on my car AND they dont do emmisions testing where i live. how gay is that....

 

find a good shop even if u have to drive a little bit.. a good mechanic will do it no problem.. just fin the right person to get them to turn there back or go buy the pipe and do it yourself.. install it.. and then go back to them to weld it up

 

I would go do it myself. Ive got access to someone who can weld. And i want to do it w/ a couple of flanges that way i can bolt it up. (plus ive already got the flanges on there from the original exhaust setup) I just dont know what im going to do about the 3" to 2" drop. Its just different size pipes on the presilencer, but if i ditch that...

 

i got one for sale if you are interested. i had a 3" dp into the 2.5" midpipe, just creates a little backpressure, not too much though. its $60 brand new, so pm with a decent offer, and we'll talk.

 

I'm going to have to go measure my catback to make sure its 2.5" but im interested

 

if you have someone make one dont say what it for. just give them the dimensions. i did and i love it. the dimensions are 17 and a half inches from the top of the flange to the top of the flange. the flanges need to be 4 inches wide from center of bolt hole to center of bolt hole. and then use whatever size pipe you need. i used 2.5 inch pipe. it cost me twenty dollars.

 

ok, so im assuming that you have the RB system. If you do, do you just have the MP flange blocking off part of the 3" DP since there is no reducer?

 

If you have a Turbo back! why do you need a midpipe?

Anyway this is what i did! Take you stock Dp, midpipe, and main cat down to your local muffler shop and tell them "i need ano of these is a 3" Come back the next day and you have a full 3" Dp midpipe ready to bolt up to your catback.

I purchesd my Dp from the rx7store, but my mid pipe cost me $12 bucks 3" mandrel with flanges.
