i dont think its good for it. u need some back pressure or it could hurt the valves.

 

My son just removed his muffler from his SRT8 300 . Seems ok . Still has his catalytic convertor and resonators . Don't think he'll have any issues . Race cars run open exhaust .

 

thats what i was thinking. i still have my cats, i don't have a resonator though.

 

The only thing will be running it on the streets, since it's illegal all across north america. Fuzz pull you over and it's an automatic tow, at least in many states.

But if it's a track or off-road only truck, then have at 'er.

 

i'm not too worried about the fuzz where i live, they are usually very lenient.

 

As long as you leave the cat on you wont have any issues burning valves. If you decide to take those out too, you will fry the valves and it will hurt the low end torque. If you are driving normal, the cops will not care, I've never had a issue my 73 charger has straight pipes, the harley has drag pipes and my ram has a gibson exhaust.

 

You may run into troubles when you go for your yearly state inspection. Most inspection stations will refuse to inspect with no muffler.

 

there is no inspection here

 

They are really strict in NH. They run an emissions test, check the tires, brakes, all the lighting. I can remember the days that an inspection consisted of the mechanic opening up the door to scrape off your old inspection sticker from your windshield and popping a new one on.

 

They do that in some places here, too, lol, which is the only way I could ever get my Jeep to pass he he (window tint too dark). They just collect your money, make you sign your name, replace sticker and voila, done. Every now and again, this guy gets busted and he stops, but always back at it a few months later!

 

i'm petty lucky that we don't have inspections here lol. it does sound pretty mean with no muffler. i'll take a video later today

 

It is indeed against your state law. But we all know there are tons of things considered illegal when it comes to vehicles.

 

sorry for my dog barking. damn dog lol. i took the video on my cell phone and i didn't know how to stop the video so it kind of runs for a few seconds after the truck passes. it's a 05 HEMI with no muffler and i just put in the DIY intake.

Sounds sweet dude, thanks for sharing!

 

Sounds good .

 

thanks. it kind of drones in the cab under throttle load but once get you up to speed and the the truck shifts up it quiets a lot.

 

i just got a heartthrob dual cat-back system that has 2 mufflers, one in each tip. i took one of the tips off, and i was wondering if i am still legal. i still technically have a muffler, its just a lot louder because the other side of the exhaust is just a straight pipe

 

All you have done is remove any back pressure,therefore it is a bit better.It should not hurt until winter when a possibility of fumes getting into yer cab.Thats all we are doing when we change to an Flowmaster,Magnaflow or any other less restrictive unit. Have fun... wake the neighbors ! LOL

 

I have a 07 1500 QC and i removed my muffler. I still have my catalytic converter and resonators. I love it

 

i have an 01 1500 and i took the muffler out and replaced it with a tail pipe extention still have the cats and i love it

 

you can't tell unless you've gone to the track that way but I bet your losing a little low end... check the Y pipe..if it's pinched, that's your bottleneck now... here is mine..I have a magnaflow with cutouts...i wanted mine very quiet in the cab for just drivin around... an sound like NHRA with cutouts open..lol

Well, i'd atleast throw on a straight pipe. But hey if theres no emissions testing, then lucky you! Just try to keep it under 95db I believe.

 

Ok I know runnin with no mufflers is against the law but I see jeeps and harleys everywhere runnin open exhaust, how do they get away with it?

 

i cut my muffler off and upgraded my cat 2 a high flow cat from magnaflow, then put a down pipe that turns down right bhind the cab. U can't even see it and i luv the sound. U can hear it a mile away and I rattle the windows in downtown.
