I have never drove in a car that had them, is it all that loud on the inside??? And will I notice a difference in performance?

 

It's not a really loud muffler. It is kinda loud inside when the car is cold it's all burbly but I like that
The sweet spot is 2-2500 rpms but like I said not a real loud muffler, it is deep though. Hope this helps.

 

Well Shakesphere, i say "NOT TO BE"


I Say do yourself a favor and get a catback, esp. if you plan to do more mods in the future,,

 

Yeah I agree get a cat-back set up. This muffler is only temporary for me until I can afford the cat-back system I want.
