I wouldnt mind trying that out, but if Im going to drop money first its going to be on the catback, and I dont know anyone currently with an X pipe for my set up I could try. I agree with Kumm the Bassani just has a unique sound thats hard to beat. I have heard his car in person and it just sounds mean!
I will say a few things on the subject. The loudest car I have heard running through street type mufflers was my friends car with a Mac catback, running shorties and an off road H. The car was insanely loud but we think there was something to the car or the set up we didnt know. The car was TOO loud for just a simple Mac Catback and off road exhaust!
I love the sound of most mufflers, but more times than not I like their sound on a 4.6 car, not on the 5.0. The pushrod motors with really loud straight through mufflers usually sound like old pickups running glasspacks, and thats NOT the sound I want!
In the end Im nearly dead set on the Bassani catback, I just want to know everything before I spend the $450 (give or take) and its too quiet!
