FS: New stainless steel SLS mid pipe with cat

I bought this pipe in August and had it on the car for exactly 65 miles. It has simply sat in my garage since the summer. With the stainless and high flow cat options, it came out to $390. While not technically new, it is as clean and shiny as the day it arrived, and I will ship it with the original packaging.

You will need to put some washers on your crossmember that I will include. I would also recommend getting urethane exhaust hangers if you don't already have them.

I am asking for $275 shipped to the lower 48. SOLD

Here is the picture of the hardware I'll be sending with it. Bolts for the mid pipe to axle back flange. 8 massive galvanized washers, and an S pipe to J pipe gasket that was only on the car for those 65 miles.

How big is that midpipe? 2.5inch?

^ Seconded. Will it fit with the stock axle-back?

Edit: Right. Cat-back, not axle-back.

Yes it is 2.5" end to end, and yes it fits with the stock axle-back, although I would call it a cat-back. The gasket on the S to J serves as the "enlarger", the flanges meet right up and since you are going from a smaller to a larger pipe, there is no restriction. The stock cat-back is a 2" pipe but the flange is large enough to completely seal the SLS. The flange on the SLS has two bolt holes that are cut oblong so you can bolt the smaller stock exhaust to it. The theory is that the exhaust gasses cool as they travel from the turbo back and the further away from the engine, the smaller the diameter needs to be, so most performance gains come from replacing the mid-pipe and multi-stage cats.

I had no exhaust leak, and there was no noticeable difference in exhaust sound. I am very meticulous about that. I once found a pinhole in my muffler because I could tell something was off. My friends thought I was crazy, but I put the car in the air and bravely got under it while it was running and followed it back, and where the brace was welded to the muffler was a microscopic hole that I could put my finger over and change the note of the exhaust ever so slightly.

Here is a link to the exact product. Use the drop downs to add the stainless and high-flow cat options.
