Showed up on time which is always a plus. In the picture and description it says solid pipe from resonator to muffler. That’s why I ordered this one. Get the box open to find two sections and only 2 muffler clamps. I’m not the brightest but I pretty sure I’m one clamp light. I completely understand if it’s a three connection exhaust set but put that in the description. It’ll work fine I hope but a little disappointed. I would have gotten the one a little less expensive if I’d have known this. Live and learn.

I liked the items. They fit my vehicle the way they should. Only thing was there was not enough clamps to put it all together. Had to get more.

Parts look great and appear to be high quality. A couple things to know… (1) as another reviewed stated, there are four components but only 2 clamps are provided – 3 clamps are required. I had to run out to a local parts store to buy another pipe clamp to complete the installation. There are different sized clamps required, so make sure you know what you need. (2) There are no bolts/nuts/washers provided to attach the resonator to the cat pipe; you’ll need to buy those separately.This is for my 2007 Buick LaCrosse with 170,000+ miles; hopefully this outlasts the car.
