I want a 3.5" or 4" i-pipe that goes from the y-pipe to over the axle where a muffler would be, and Mufflex won't sell them seperately, just as a $500+ kit Anyways, does anyone make just a i-pipe in these sizes? TIA, Shawn

Not that I've been able to find . . . I've been looking for the same thing. I'm about ready to order some 4" mandrel bends and straight pipe from Stainles Works and build my own. It will still cost $500 for the parts, but at least it will be made out of stainless steel. Just tried welding some stainless steel tonight for the first time, and it was easier than I thought.

If you want to build your own custom 4 inch exhaust out of aluminumized steel, you can get it done pretty cheap.

I use 3.5" I-Pipe to 3.5" cut-out with QTEC and then reduce to 3" to go over the axle and use my SLP D/D muffler. Cheap and easy for an exhaust shop to do and flow is adequate for track use.

Sean, I found a local source for 4" J-bends... That means that a foot or so is straight, and the there is a 90 degree bend. Each piece is $34, and it's mild steel. I have been looking for the same thing and don't want to buy a $500 Mufflex catback that I then need to hack up to suit my purposes.
