is it possible to have one thats not tail-shaft mounted?

 

You sent me a PM asking about my torque arm. Its a slightly modified Spohn unit, bolted to the floor. Definitely not X-pipe friendly.

 

I think I found a way that i can get it to work if i move the X up further towards the collectors, or, just use an H-pipe instead or something. I can get creative and make it work lol, or just run w/o the X and just have straight piping.

 

I put the narrowest part of my X right where the g-load brace dips for the exhaust to go thru. Spohn TA also.
