check it out guys. i went to my local muffler shop and got a price on the exshaust to the muffler and everything included. the price is $175 BUCKS. sounds good to me. and yes its a flowmaster 40 muffler, hehe. but, the guy at the shop said i should run 2 1/4 all the way back. i told him that this web site, inliners.org recommends i should use 2 1/2. he says i will lose low end torque with 2 1/2. what u guys think about that statement? any further advice and comments would be helpful. thanks again.
