On mine, I used Flowmaster 40 series at 3 1/2" pipe. Had the friends at Midas bend my tailpipes for me and Used new Hooker headers with Ceramic coating.Ran 3 1/2' pipe all the way. Used sound Deadening stainless steel glass pax tips on the tailpipes. Really quiet!!! Nice quiet tone when hammering down the road. All the parts came from Checker Auto Parts. The Mufflers are stainless Steel as well! No burn-out types!! I did mine in Duel exhaust as it had no catalytic Converters on it. hope this is what you were looking for, Dan

Yes it is. True Duels with headers and Flowmaster 40 series and Chrome/ Stainless steel with built in Resonators! Nice quiet engine and very little back pressure for sure. Between that and the cam and other goodies i am getting around 10- 12 MPG. Not to shabby for an oldie!!

Been on for two years now and about 500 miles. More coming up on the millage. No issues at all!! You were using Flowmaster's?? Never heard of that one! Mine look like new and made of Stainless Steel. Look almost like they came out of the box! Were almost $200.00 each! I was told that they are the same ones used on the Banks Power pack system.
