here's a link to a muffler on ebay, it's exactly the same as the one im selling. Also included on mine is a rear section pipe welded right to the muffler inlet. The pipe is custom bent to fit a P10 an will bolt right on to any P10 stock exhaust setup.
it's definatly an aggressive muffler. It's pretty deep sounding, not annoyingly deep, just about perfect sound(i thought anyways). I only had it on my car for about 2 months an I loved it the whole time. The laws in Maine on modifications to your car are very strict tho, your exhaust can't be louder then stock so i ended up having to take it off. Overall i paid $250 with shipping an having the custom pipe built. Make me an offer tho, ill probably sell pretty cheap.
