Just wanted to say that I got Rienhart's Cobra kit installed on my car last Wednessday. The kit it self is excellent. I really noticed a kick in performance at the mid to upper rpm range. The car breathes a hell of a lot better on the top end. However, I must say the noise level barely changed at all. It still sounds relatively stock and I even have 2 1/4 18 inch Magnaflow mufflers. Hm, I think I am going to have to go with 2 1/2 18 inch long glass packs after all. Anyway, I must say I am happy with the kit. I also think the car lost some weight. Thoose stock mainfolds and cats are freaking heavy! Gas milage seems a bit better to. It isn't that I want it to be a neighborhood waker. Just a little more roar would be nice. That is something I will work out in time but I really don't want delete tips. I think that would make the car too loud. Anyone else try glass packs on a Marauder? Just curious that is all.
