No exhaust

[Glo]

I agree that a setup like Cleave's is not going to burn any valves. I've heard many people say that running open headers or a very short exhaust will burn up your valves, but I've never seen it personally. I understand the theory behind it, but I think it's somewhat of an old wives tale. The theory stems from the fact that a much more open exhaust will have less back pressure and allow atmospheric air to make it's way to the exhaust ports on the cylinder head. Atmospheric air is made up of approximately 21% oxygen... exhaust gasses are approximately 1% oxygen. The thought is that the reduced back pressure will allow this additional atmospheric oxygen to reach the combustion area near the exhaust ports and act as an accelerant in the combustion process and burn up the valves... especially the exhaust valves.

I've had and known many people to run exhausts like Cleaves even with no catalytic converters for many years and many miles with no problems.


If this were true, I think a lot more old school planes with the individual stubby exhaust tips would have fallen out of the sky because of burnt/stuck valves.

I was running without anything back the resonator for about 1000miles after my Corsa muffler broke ; usually reving right near the limiter and pretty sure my cats have burned up / melted. Been having a check engine light - error code 0430 starting a couple of days ago - went away - but started again today. Been offroading hard last night and rear had almost a burning smell of something I couldn't track down.

Not sure if it is related to the short exhaust - or just coincidence.

I removed the muffler but kept the res on. If i were to install a pipe to corral the exhaust away from underneath the vehicle, how would y'all recommend to do so?

I tried this and it lasted 1 day ! It was loud and sounded great while under the throttle but other then that, I just couldn't manage it . So i went down and had the Resonator put back on and had a solid 3' piece of pipe put in where the muffler would be and had the shop make a custom 3' into 2.5' Y-pipe and connected the rear tail pipes and ran it out the back . Sounds great, nice and throaty, no drone, rumbles good and when you get on it it sounds healthy. Im very pleased

Im only using this as a temp set up . I'm seriously looking into a turbo system for the truck in which all of this will change again . But for now it sounds great !

I have recently driven a vehicle with real drone, a raptor with the catback removed has no drone, period, my truck never makes the racket that piece of crap did

Also no drone here. Just louder then shit. And I love it.

I'd have to say that my exhaust removal has been my personal favorite mod so far. My lights look cool and are super useful WHEN I USE THEM. My bed rack looks cool when people pull up next to me at a red light and stare. But my exhaust is something I get to enjoy every time my foot is on the gas.
