How bad is the drone? Around what rpm range is it noticeable and can you hear it with music on?

Here it is. https://www.magnaflow.com/products?partNumber=11114

Thanks the info on the specific muffler and for the additional videos. One last question...do you know if any cutting, alteration, etc had to be done to get the 11114 model to fit well? Or did it go on with no issues at all?

Any CEL’s with the muffler delete straight pipe? And are you guys referring to the rear two mufflers being deleted?

Also, for the magnaflow muffler route, we’re these being cut and installed in the rear two mufflers? Any CEL’s with doing so?

Thanks guys!!

hey man what model number mufflers did you use? Any sounds clips of your exhaust journey?
