Bought these from americanmuscle.com for $350. Had these on my car for literally about a 1000 miles. They are practically brand new. I dont have the clamps for them because i reused them for my new exhaust. You can probably by clamps for under 5 dollars, not a big deal. These things sound amazing!!! I took them off because i recently put on an o/r x pipe which makes it way too loud. Check out my video on youtube. My username is killaconnect91. Look for SLP warm start. That video is stock with just SLPs. Trying to get around 225 if possible. Make me some offers!! Thanks
