From the twin cat's back, they fabricated 3" mandrel bent tubing that was coated with heat resistant materiel.

Since the car has 2 mufflers, I asked for only one, then they called me and said I don't want only one, it's too loud. And this guy races P-Cars so I'm guessing he knows loud.

At any rate, he went with a dual stage muffler for the first one, and a single stage muffler for the rear, he cut out 2 holes and welded dual 3" pipes on the rear muffler.

They were flowmaster 40 series mufflers, in the 4x9.75 size. You can check them online.

It was loud, I got a kick out of it. In terms of cost, it ran me just under 1k for parts and building/installing the system.

Hope this helps.<ul><li><a href="http://www.flowmastermufflers.com/">http://www.flowmastermufflers.com/</a</li></ul>
