I just installed DS10S and DGU11 . They were not that tight of a fit. But I had to remove and reinstall them together for the correct geometry. They sound great. Manifolds wil quiet mufflers and tailpipes and it is still pretty loud outside of the car. Inside it is nice and quiet. A small amount if any of get-up from the start and no lose of top end with manifolds.
Granted I am less then 400 HP. I would recommend the Pypes numbers above and manifolds.
