well i think im decided on the 409 duel exhaust before the trans upgrade (can only spent so much at a time) the best price i have found is 719.75 is that good or does anyone know a cheaper place? thanks


P.S. should i leave the cat in or not? i eventually plan to add an intake...:ro)

Been pondering the cat removal myself. Wonder what the dealserships say when you take it in and they notice it missing?

Has anyone looked to see that the diameter of the CAT pipe is?? Perhaps simply gutting it and reinstalling the shell or even putting the shell over a 4" pipe could solve the problem of dealership snoops causing trouble??

Just a thought . . .

hi hass-lly replacing the turbo pipe will make the exhaust a bit louder. also replacing the turbo pipe will also lower your egt temps. really only ness. if hauling and towing with a big heavy right foot. the part # for the head-turbo pipe in stainless is gms9401.

at first i got rid of the cat. then about a week ago i got rid of my muffler too and cant be more pleased with the soundof the staight pipe all the way back. i have not gotten any codes or check engine lights either. it sounds mean.
