see the price of the ws really makes it not worth it for me.. i run a freakin y7.. i'm just looking for something that looks a lil better and sounds a lil better than my stock 2" tube sticking out the back. i mean gaining a whole like 4whp for 400 bucks is not what i'm looking for. just something that looks a lil better(4" outlet is all i'm looking for) and sounds a lil deeper.
what is the es tuner? never heard of it
