13 Second V6 Catback with a Twist

Compliments of WarShrike @ www.fullthrottlev6.com

So I finally got a different catback to replace the TSP Rumbler. The wife complained a bit too often even when I'd drive trying to be mellow and not let it go over 3K rpms (no small feat with a 3800 stall).

I decided to start putting together a catback with the 13secV6 catback as a guideline. The serial numbers have changed since that thread was started, so I'll try and give you my best finds. I must note that I had to have a new y-pipe fabricated to work as the slip-fit setup as I got rid of the v-band setup as they were constantly snagging on things.

I did make a departure as the Summit Turbo Muffler had the dual out on the same side of the muffler instead of being a transverse setup. I went with a Dynomax Super Turbo Muffler that was 3" inlet and 3" dual outlet in transverse location. I couldn't find any 3" tailpipes to use, but figured I'd just have it done at the exhaust shop.

Parts:

Flowmaster 3" intermediate pipe: FLO-26087

Dynomax 3" Axle cross over pipe: WLK-53061

Dynomax Super Turbo Muffler 3" inlet 3" dual outlet: WLK-17670

Impressions:

Very mellow startup that still has a nice rumble compared to stock but won't attract too much attention with the cutout closed. It gives the car more of the grainy V6 sound instead of the scream from the Rumbler. I can carry on a conversation with my wife and the radio going without too much issue. No drone either inside the cabin.

I can also go WOT without people half a mile away knowing I'm coming.

This will offer much more of a sleeper standard for me which is what I liked. It sounded like I was trying to race everybody with the Rumbler, though I was part throttle all the time.

For those that are wondering, I sold the Rumbler to another V6 owner in the area
