Just coming back from the test drive after the golf tee mod. My initial reaction was very positive. Standing still, it's definitely a much deeper sound coming from the right pipe. However, I think that set my expectation too high. The difference is barely noticeable on the road
By the way I bought the set mentioned above but couldn't find one that fits on to the metal part. I got the plastic tube already but I also want to cover the metal opening. Any suggestions?
