Size of Bonneville DP?
When i got my tips put on today, i asked the muffler shop for a quote on a 3" DP. He went over and told me I already had a 3" DP. This is measuring with his hand, so he could be wrong, but anyone have info on this? I think the Series 2 L67 might be different, but I am not sure.

The DP is the pipe going from the crossover, to the cat. The pipe after it is called the flex pipe. All of that should preferably be 3".

I would go to a different exhaust shop, cause your downpipe should be 2.5", oh also, most exhaust shops can do the 3" downpipe but it will be press bent or worse wrinkle bent, i plan on doing a 3" downpipe in the future and im gonna buy two 45* mandrel bends from summit or jc whitney and have them welded together and have a very similar setup to the m&* downpipe that sol has

With the crimp bent DP everything should cost under $150.

I had my cataclysmic perverter replaced with a high flow unit. They didn't weld it back in quiet right. I purchased a 3 inch exhaust clamp to rememedy the slight tick noise and it was about 1/2 inch to big. I then went and purchased a 2.5 inch and it was dead on . My year model is different however .
