"You have convinced me to look at the Dynomax Super Turbo. Is that part number ST 17749? I want to have a good deep sound, but I don't want it to overpower everything. Any comments about whether I should have an X or an H pipe? Many thanks"

From what you have said, I am sure you will like the super Turbo, especially the longer case version. I have run the ST on 3 different engine combos, and was never disappointed.

Regarding X or H... I have used both on my current engine, but it is not an entirely an apple's to apples comparison. With the X I was running the long case ultraflow, and with the H am running the short case ultraflow. As expected the short case is louder, but the H tends to create more of a deeper rumble as compared to more of a "whine" with the X. Think NASCAR'ish sound with the X. In hindsight, I would have used the X in my new combo due to the louder short case ultra flows.

Many here have way more experience in this area than I do, but that was just my experience from a limited field of test cases!
