    • Works well 08 Grand Prix
I bought this to finally fix my grand prix resonator. I had been patching the resonator every year with a sheet-metal panel and steel wool (which works well, when clamped on to the old resonator). I installed this in a couple hours, needing to modify the existing exhaust to match the length of this resonator. If you won a sawzall, that is not a big job. Its basically like legos, and should not be something that would scare you off. Cut the exhaust to fit (precision is not really necessary, just get close), and clamp the stuff together. Seriously, if you are buying this as a replacement, your car is probably a hooptie - just fit it in there in an imprecise manner and clamp together. It will be quiet and last longer than your already-well-used-car will. I wish I had done this earlier. ... show more

when I orderd the resonator, it only took 2 days to get it. I took the old one off and put the new one on,but my tail pipe was 4 inches to short. I got a 4 inch sleve and 2 climbs, everthing work out ok. The walker resonator was well built. I give it a 5 star.
