Valvetronic X-pipe w/HFCs: $700

Used for 1k miles.

I'm the 2nd owner of this X-pipe which was used briefly by original owner for about 1k miles. It's been collecting dust in my bedroom ever since as I decided to modify my stock X-pipe instead.

A note about the cats: They are 150 CPI, not 200 as advertised by various resellers. I know this from taking a picture of the cat core with a probe camera and painstakingly counting the cells. Since the pipe is made in China and 150 CPI cats is a rare sight, I suspect the cats are from HKS, one of the only manufactorers of 150 CPI cats in the world that I know of. The reason I investigated the CPI density is that multiple people reported an exhaust smell with this pipe. This normally doesn't occur with 200 CPI cats but it does with 100 CPI cats (like Akrapovic's). Thus, a 150 CPI cat may also produce some smell.

Macht Schnell test pipes: $125

Used for 7k miles. Band clamps included.

Bimmerworld's [Magnaflow] Race exhaust mufflers: $250

Never used.

I'm selling only the mufflers and mounting hardware since I've cut off the connecting pipes.

The mufflers are brand new and still in original packaging.

GLWS My car had this exhaust on it when I bought it and honestly it had a perfect tone to it! and the tips are huge they looked awesome. only downside is it just a dual exit instead of a quad.

mannn, where were you two months ago 😢
free bump, i think it would sound great with a catless x-pipe and a pair of resonators.
