for about $20 more per side you can get Magnaflow universals. Mine have been trouble free for about 60K. A couple others have used them too. Lifetime warranty...and they have been tested.

 

I was able to get back to the shop and they fixed her up. So now i have a solid y pipe that goes into a cat and flowsound muffler which are both tucked in where the old muffler was. Overall I'm pretty happy, they did me right.

 

Good to hear. I went with a Magnaflow suggested dealer and they hosed the install. Even had a clamp on one of the cats and welded on top of that... I pulled it off and fixed it myself, and when I complained to Magnaflow, they sent me 100% of my money back and took the shop off the dealer list. Nice to see poeple stand behind their work...
