I'm selling a used Heartthrob Cat to Axle exhaust, it's 409 stainless steel and has the H-Pipe and Resonators. These are only a few months old, but I'm selling them because 3" pipes don't fit under a lowered car(so I found out). They sounded great paired to bassani mufflers, not much louder than stock but had a nice deep rumble. I had them on for a month, but they kept bumping into the underside of my car and drove me crazy so I had to replace them with some smaller pipes. These bolt up to the stock cats back to the mufflers, and I have all the hardware it came with. I'm in Kansas City if anyone wants to pick them up, or I'll ship them for $475 total.
Edit: Price drop to 400 shipped, 350 local.
