Chopped these stainess mufflers off my old Neuspeed exhaust, you can have them welded in place of your OEM mufflers or use them to build a custom exhaust. They were fairly quiet but my whole goal since buying my car has
been fully OEM. $40 each or $60 takes them both.

I only cleaned up a bit of one for the pic, but they'll buff out great, you just need to spend 15-20 mins to get them to shine.
