Muffler Reviews - 1991 Jeep Wrangler
Walker | 18341
 


this muffler fit perfectly, was quite simple to navigate the web site, and seems to of good construction. however it did take too long to arrive and is a bit louder than stock .I will see how long it lasts but should be fine and was a very good price point..
