Louder Exhaust!!

[my9250GT]

That pretty much what i'm running now the 40 series mufflers no tailpipes and no turndowns.

here is what i just discovered when the car was stock i bought the flows and had them put on with the stock set-up.
then when i got the headers and x-pipe i took the car to my mechanic and had him install everything here is what he did.

he installed the headers and 2.5 in x-pipe but instead of cutting the 2 1/4 inch stock pipe from the flang that comes from the old h-pipe he just bolted it to the new 2.5inch pipe.
so now i have about a foot of 2 1/4 pipe mixed in with 2.5 inch pipe..what a ******* thats why its is not as loud as the others.

thanks for the replys.
