i kept trying to search but it kept refusing the "3" " so i give up. does anyone sell a 3" midpipe that will bolt up to the stock catback and possibly a aftermarket catback later? if so can i have a link?

second item on the page....is this what youre lookin for?

 

Yeah, RP is a 3" midpipe.

 

indeed. & i want one. now.

 

thanx guys thats awesome but i meant to say catless w/ or w/o resonator

 

ok i scrolled down and i'm an idiot but are there any others that aren't 300 bux?

I just sold a used one to a guy in Scotland ... too bad, it was up there for several weeks

BTW, put an asterick after short search terms --> 3"*

 

I got the rx7store.net midpipe for the rx8. It's 3" and super neat. I got the catless resonated one.

 

turboxs makes one plus they make a whole 3in system

 

The only downside to the 3" midpipe is that you have to carefully stretch the factory braided "doughnut" to fit the pipe but it was worth it. I used a standard exhaust pipe stretcher.

Doesn't theirs only fit their catback muffler system?

 

Yup, that's TurboXS said.

 

What about the the 2 factory O2 sensors? All the racecats and midpipes I´ve seen only have one connector on them?

 

the front sensor is in the exhaust manifold, only the rear sensor is in the midpipe

 

I stand corrected...

 

ok wait a tick so what do i have to stretch to put on a 3" midpipe? pics?

 

When you remove your factory midpipe/cat, the end with the two nuts/studs that fits in the "cat-back" portion will have a braided stainless steel "doughnut" that seals the two pipes together. This doughnut will need to be retained. However, because the factory exhaust at that point is about 2.5" it will need to be slightly stretched to fit the new midpipe. Pics? Nope. It's a pretty easy operation and the pipe stretcher is available at the parts shop. Or, if you are friendly with the local exhaust shop they may stretch it a bit for you.

The RP pipe reduces down to the 2.5" outlet size to fit the OE and aftermarket exhausts

 

ah and yeah i saw that sale team i definately kicked myself in the head over that one. damnit

 

Team, is that a recent change they made? I got my pipe from RP two years ago and I had to open up the doughnut. Either way, getting rid of the cat is one of the more effective ways to get more power out of our engines.

It came with a group of parts I bought used, you can see that donut tube extension is smaller than the main 3" tube, it measured 2.5" OD, I never installed it and am assuming the donut just slid on, maybe I'm wrong ...

 

yea the donut just slids on to that part of the midpipe.

 

which makes more power a 3" or 2.5" it will be used with stock zaust till i can afford turboXS or Agency power

 

I've got the racing beat catback. when I look for a midpipe, do i need to plan on stretching the donut? Or is there no longer any donut... also, since the RB intermediate pipe is 3 inches, what is the effect of having the RP midpipe that reduces down to 2.5"? Sorry bout the thread jack, just a relevant question, i think...
