These are extremely difficult to install, especially the drivers side rear (2011 Tahoe), but did ultimately fix the manifold leak I had. Product was as advertised and seemed to be of high quality.Do yourself a favor and search the internet for videos/forums to help with the install. It is impossible to get get the drivers side bottom bolt started working from the top. Working from underneath the vehicle, I removed the heat shield and slid the drive shaft over and then it wasn't too bad, but wasted a lot of time before that.

Work great saves a lot of time from pulling head. Passenger side easy drivers side kind of pain to get bolts started.

This eliminated my exhaust tick so I'm satisfied with the product. installing the rear passenger clamp was relatively easy, id recommend removing the inner fender first so you have better access to work.HOWEVER the rear drivers clamp was much much more difficult to install. I get it, its only 3 bolts but the issue here is access, I had a friend help me and it took us over 3 hours to properly install this clamp. Don't get me wrong I recommend this product, just be prepared to spend some time on this install, it will drive you nuts but you will be glad when it is complete and your issue is resolved.

Worked really good closed gap no more exhaust leak

Good tool and easy to use good price
