True Duals or Catback Exhaust???
My eyes burn enough from the ory and borla cb so I wouldnt want dumped duals. Originally I was going to do them but decided against them for that reason and also I wanted a catted Y (gutted) to pass visual emissions if needed.
Also after the stall I cant imagine tds on the street going past cops.

I can laugh now but i was shitting kittens.
I hear all the talk about how loud true duals are over the cat back system ,but how much power gained from a catback to true duals , (Not trying to hijack just putting this question out for the other who wanna know too).

I have true duals with no cats on my car and I love it. At idle I don't think its much louder than a car that has a ORY. No rasp at all. I haven't scraped anything with them, but then again my car hasn't been lowered yet.
I vote catback with an E cutout under passenger seat. Never seen a true dual setup I really liked on these cars. Hate the under the axel ones and the two pipes going down the pass side ones. I really don't think they sound better either.

True d's or a catback is alot of money for no real power. a cutout is low cost and you can open or close it when ever you want. They gain as much or in my cars case 30hp when open. way more then a cat back or true d's will gain. get a cutout and spend the saved cash on something extra.

I have had Longtubes/ORY/LMI and Longtubes/X-Pipe/Dumps. The overall volume is not much different. The quality of the sound is where all the difference is. A nice dual system has a much cleaner sounds. Muffler choice is where you can adjust your tone and volume. Most duals are loud beasue space is at a premium, and most people run a bullet style muffler for clearance, which are almost all fairly loud. Ultimately, a cutout will not produce the same gain as duals, due to the scavagening effect of the crossover. Is there a definite possiblilty that it will be a small difference, absolutely, will it exist, absolutely.
I've heard the kooks TD system in person with hi-flo cats and it's not loud at all, even with a high 230's cam. You can't even hear it over my Kooks LT's, hi-flo cats, and GMMG.
Refer to link below. Isn't the original link i read about exhaust scavenging but it'll do.

I could carry my dual system easily with one hand. Most of them are less than 6 feet long from collector to dumps. I could say the rear section (over axle pipe, muffler, tails) of my stock exhasut weighed more.
That's exactly why id choose True duals aswell, nice drop of weigh over a FULL catback or OEM with cutouts.
