I am looking into putting gt takeoffs on my car. The main reason i am doing this is becuase i read that 2.25 inch exhaust is the way to go on V6's. If i buy a pacesetter dual exhaust adapter and run the cat back strait from that, will that be a good setup? Also depending on the money situation, i may have flowmaster 40 series put into the system. Are the 40's the best choice for a deep tone?
