Has anybody just taken the muffler off? I think it might be a tad illegal, but im thinking about doing it....Is their any problems this could cause? Has anybody done it?

 

i ran it muffler less for .. 10 minutes. i then put a streight true magnaflow. i think the sound is not that much different. just try it. the hardest thing is to remove it from the rubber... thingies.

 

wouldent cause any engine problems would it? Im workin on it right now

 

I'm not sure but I think the engine needs a cerain amount of backpressure to be efficient. Taking the muffler off might make it sounds cool but degrade your performace.

 

I don't know I think that the stock muffler may choke out some power.

Not a big deal but I'm suspicious.

 

its off and it sounds awesome!! it just sounds deep. Basically sounds like it looks!! I deffenatly think im going to keep it off..... until my next inspeciton that is.....

 

Not back pressure, but an appropriate pipe diameter to assure velocity without restriction. A large can creates a larger heat sync, and loss of heat contracts exhaust gas, slowing it down.

 

so Jpop, are u saying theirs not enough back pressure to do this? or am i in the clear?

 

Back pressure isn't an issue nor solution. You put a fat pipe on your JK you'll lose exhaust velocity, just like the tuner crowd. Then someone from that crowd decides that it's "back pressure" that needed, it's not.

So as long as you run the stock size 2.5" pipe you'll be cool.

 

Your right it does sound cool, But so does my Gibson, I'ts pretty loud, to but it might just be my imagination but I think it's mellowing out abit, Most runs I've been on require Spark Arresters in the wooded areas. I.E mufflers.
I actually lost about 1-2 mpg with the Gibson, Small price to pay -- lol.
