just saw this and never even heard of it till now. Now I'm pretty interested. Being able to swap from stock sound exhaust to something more aggressive when I want sounds good. I don't know much about exhaust but thought that an open pipe before the muffler can destroy your catalytic converter after time? if that's false, anyone know any potential problems with this kit?

I knew a couple guys that would use electric cutouts in the drag racing scene, but they make it a straight pipe exhaust and it's really loud.

Buddy used to have one on his Trans Am. Sounded great. Fairly easy to install.

Used to use cable operated (like bike brake cable only stouter) to open them to race or just make noise, no converter though so I don't have the answer to that.

interesting, I've always had flowmaster on all my trucks but decided against exhaust on the jeep since it seems SUVs seem to hold in a lot more of the noise. I guess I'm just gettin old :/ I had an s10 at one time that the exhaust pipe rusted through just in front of the muffler. I thought it was cool and sounded like aftermarket exhaust till about 3 weeks later I lost power and was flooring it doing about 40 on the freeway. shop said cause the lack of muffler, my cat got cold and went out? anyone confirm if that's common or if running a straight pipe can do damage to the car?
not sure if there's room but thinking maybe adding a flowmaster on the driver side in addition to stock exhaust on the passenger. it would look like dual exhaust from the back but one side be flows and the other stock. the cut off valve could just let me pick and switch to stock when my parents, wife or baby's in the jeep.
sound crazy? :/

I think there's a variation of this on some of the ford raptors? Pretty cool

Some offshore boats run these exhausts, called silent choice. It allows you to choose loud or quiet

When they say it ruins your cats it is referring to your cats getting clogged. The lack of back pressure over time can cause unburnt fuel to enter the cats clogging them up. Now, this can happen to any cats on any vehicle overtime, but the process is sped up with modified exhaust. But all in all if that were to happen it would just be a good excuse to get some nice high flow cats or get rid of them all together.

gotcha thank u for that info. getting rid of the cat or upgrading would be nice but we got these pain in the ass things in CA called smog checks:/ thinking ill do the cutout and put a flowmaster 40 on the drivers side, stock on the pass.. I guess that's dual exhaust, right :/ dunno
