I am runnig long tube hookers, into a modified mufflex y-pipe (to fit around my Spohn TQ arm), then run this into a mufflex spintech cat-back system (no cat of course).

So my exhaust is all inboard. People seems to be very conserned with SFC and stock exhuast clearance. I don't care about this at all.

What are people doing that don't have these issues to worry about?

Is it better to just fab up my own stuff. I can do some simple flux core welding. Thats how I moded the exhuast.

 

I fabed my own Y pipe to get past my SFC. Although I am thinking of trying to do another. Mine was quick and dirty and I want to try to run dual 2.5s a little longer before the merger. UMI Subframes

 

I run spohn subframes. They come with two small bars to tie intothe trans subframes. I mounted those bars as high as i could against body to clear exhaust that ran past it. I had a 4" custom y and now duals with xpipe in that location. Fits good. I'd fab your own if you can weld and have a sawzall lol. Exhaust is easy

 

UMI Subframes and custom modified Y pipe I bought used and cut up.

I have SSM SFCs (best ever made for our cars IMO) and have had both the SLP and Mufflex y-pipes. Both clear without issues.

 

Check these out. Good inside and outside designs.

I bought UMI but haven't installed them yet. Now that i'm doing an LS1/t56 swap I'm curious to see if they will fit with the LT headers and Ypipe I use.

 

im right there with ya!!on the SSM parts

 

With all your exhaust in the trans tunnel, what SFC will not clear? I don't recall any design intruding into the tunnel

 

None. I just wanted to know what people found best when they don't have to worry. I like BMR stuff, so I might use that and add addtional supports to it.

 

I bought the Jegsters and added two supports to go over to the trans tunnel. Plenty of ground clearance even with 4" exhaust.
