I was looking at the Motordyne Shockwave the other day, I currently have the ART pipes and XYZ with HFC... I find it strange that, unless you go full decatted, you have to use the stock cats or non-Motordyne HFCs as the XYZ+HFC won't fit with the y-pipe back parts of the Shockwave. A bit annoying really considering the front, y-pipe part, of the Shockwave is the same as the XYZ.
What the eckin peck, that's crazy. I thought the whole point was that the modules were interchangeable and all their stuff actually worked together.
Doh. Well, if you do get it, i'd love a listen.
Tell me about it! If you compare the middle section of the Shockwave vs the XYZ pipes below it in the following link you'll see that the x-pipe section of the Shockwave is in the same location as their race cat and the exhaust is dual after that so I can't see how you can use the Shockwave without normal cats or berks or something!
