Does coupe HFC fit sedan? how about y pipe? I know the CBE are different, what about front end?

 

Cats and y-pipe fit.

 

I believe the midpipe fits too, but don't quote me on that.

 

The headers, hfc's, and y-pipes are interchangeable between coupes n sedans

 

Alright! thanks!

 

i thought the diameters on the sedans and coupes were different? i specifically remember being told that coupe parts and sedan parts were NOT interchangeable. that honestly doesn't make sense though (why would any given company put in the effort). i know for a fact though that my fast intentions are 2.25 in diameter.

 

Diameters may be different but the parts are interchangeable. Im running hfc's and a mid pipe off a coupe on my 11 sedan without any issues.

 

I thought coupe mid pipe is single and sedan is dual pipe, how does it fit? could you post a pic?

 

Parts are interchangeable but the pipe diameter is different. I learned this after talking with Tony at Fast Intentions a year or two ago. Supposedly sedans are somewhere around 2.25-2.375" and Coupes are 2.5".

 

100% confirmation would be ideal on this. If this is in fact true then a simple swap to coupe manifolds, cats and midpipes, would be a power increase for the sedan. and probably cheap as well.

 

Don't get people confused , MID PIPES and REAR MUFFLER sections on coupe and Sedan are different. Manifold, cats, and Y pipe are the same - fitment wise.


...back to tubing size, I had started a thread a LONG time ago trying to get people to post exact sizes of their OEM sections to confirm exactly what is what, but it didn't get much attention. My comment earlier in this thread about talking to Tony was about Cats. So, I know for sure that the cats sizes are different. I'm not sure about manifold size, it could really go either way. OEM Y pipe, from pictures I have seen, appear to all be necked down to the same size.
