Default True Duals PLUS Cat-Back. Which Cat-Back?

So I found this on here. Can't remember who this belongs too sorry, but it's ******* sweet and I want it now. I am one of those guys that has a cam and dumped duals and has to leave at 5am from my apartment complex, starting a cammed cold engine under a rattly metal carport and feel bad for waking my neighbors, but still love my duals so this is the perfect solution in my eyes.

I like this setup because with other cutout setups i have seen the pipe for the cutout just comes off the main pipe at like a 45 degree angle allowing a lot of the flow and sound to continue to travel out through the tail pipes. In this setup the cutouts open and it's a straight shot out for the flow. Most should bypass the over the axle pipe. This setup also benefits from being able to clear the axle easily and being able to hang a stock style cat-back on stock hangers!


Planning on running single chamber flows where the bullets are in this setup. The texas speed duals have a little space between pipes so hopefully I could fit 2 single chambers side by side, then run the pipes together in time to hit the combination pipe.

What cat-back would you run behind pacesetter lt's, tsp ORX, and single chambers for when the cut-outs are closed? Still want to have a little mean sound but mostly want it to be quiet for early morning/late night courtesy.

I would run 2 3" e-cutouts where the caps are in this picture so I don't have to get under the car haha.

I think if I were to invest the time and money it would take to replicate this setup, I would continue with the true duals all the way back into 1 muffler before each tip or a dual in dual out style muffler.

I was actually planning on doing that setup on my 98. Id stick with a SLP dual dual or Magnaflow for noise level and price

With that though you only get too loud or too quiet. Plus you have to deal with running 2 3" pipes over the axle which is more of a bitch i'd think than to weld this up. This allows for the hanging of a cat-back in the stock location for temp use, and cutouts for duals sound when it's not 5a.m.

Think that would sound alright with the exhaust running through single cahmber flowmasters, then through a dual dual muffler? I am sure the sound level would good, but the tone may be a little ricey ya think?

I took that system off a car we were de-modding. I have other pics if you need them and the system was sold to another friend of mine - Im sure he'd take some pics if you needed them as well. System, honestly, was built in Mexico...

Awesome. Seems like this would be pretty easy to do.

Can you think of any advantages of this setup over one with traditional y-shaped cutouts right after the bullets and then having the two pipes just run together and go over the axle?

IMO, without a doubt the SLP Powerflo is the best non-annoyingly loud sounding catback for a LS1 F-body.

You could aim the passenger side at the rear seat hump where people often put cutouts... Only issue I could see is where would you aim the driver side?

Sorry, no

The car it came off of was bone stock besides the longtubes/exhaust and a LS6 intake. With the caps off, it was loud but had good tone and rumble, nowhere near as obnoxious as a Loudmouth. Closed, it was factory quiet. No ****, it tucked so well, we had no clue it was true duals til the car was in the air
