Just wondering if anyone ever put one of these on and what the outcome was. I have a couple 40 series race car mufflers in my garage I thought about slapping one on.

 

flowmaster makes a muffler specific for diesels, i would look in to that before i would put on the 40 series.

 

I have heard it deffinitly an interesting sound you hear the knockin deisel coming and then it sounds like every other flowmaster leavin deffinitly makes you look twice when it drives by. Not a fan myself

I don't think I was using the 40 series mufflers.. it was one of the race mufflers... 3in in and out... it was 9ins long.. I think it was a single chamber.. It did not have the gasser sound.. but it was a little different... I really did not notice much difference EGT difference between it and straight piped.. but it did knock the noise down a little...
