Used Perrin axleback for sale. I bought the whole exhaust and decided to keep the mid-pipe and y-pipe and part with the mufflers. Initially I tried the axleback on the stock y-pipe and they sounded great. But too loud for me without the stock resonator and with 3" piping (I have a catted Invidia DP).
Full disclosure: There is no rust, but they have various crap on them - but can be polished to perfection, if someone has the time. One of the tips has a small dent in it (most of it hammered out and it is hard to notice anymore). There are a few scratches on the bottom of the cans from driving down a steep driveway and a high curb. But the cans work and sound great.
Asking $250 + shipping. Located in Cincinnati, OH.
