Muffler removal

[DifferentPointofView]

'm not sure if it would hurt or help, but my friend has a removable muffler on his honda. He jacks up the back of the car, takes the tire off, and theres just a clamp holding the muffler on. Takes about 5 minutes.

Same here, except I don't have to jack up the car, I've got enough clearence to get under and cut the time in half taking it off. I just wanna test it with another tank.

A friend of mine took the muffler off another friends Jeep I6, and it basically sounds like a v8 with a flow master exhaust. It's not much louder than some people with flow masters. Also, the sound won't bother me. I hear it everyday from people with nice pipes, also I'm in a band and when we play shows, we mic. everything, we mic. amps and we mic. drums. So basically our ears get blown out. I've also got a 2400wpeak amp blasting power at me constantly, so the only concern I'm gonna get is I can't listen to music and exhaust at the same time unless I don't wanna hear next year.

Oh, and I don't know about your chicks, but around here, chicks dig the loudest exhaust pipes

All the chicks around here work on cars the same amount or more than the guys around here. They're into nice pipes. It's like the chick that rides a harley. She's into the masculine rumble of the exhaust.

Why yes, isn't that how you get to be the alpha male?

It sure is nice talking about gas mileage here.

Don't do it. A Jeep inline 6 without a muffler sounds like a bad running tractor. Besides, in some locales, you could easily exceed sound ordinances.

My old minivan with a Cherry Bomb glasspack was plenty loud. But you will drive it with a softer foot.

My attitude concerning FE is:

1) Safety is first
2) Courtesy is next
3) Driving for FE is third

Nobody will complain if you are NOT making excessive noise.

If I were courteous I'd be driving 65 like everyone else, but I guess not cause people get mad at me for obeying the law anyway. Might as well make some noise. I probably make the same amount of db's from my sound system anyway as without a muffler.


Ran into a problem. Muffler U-Clamps are frozen on there (more like the nuts have melted to the bolts). Instead of hacking them off, I'm just going to try more back pressure for more low end torque since running down the highway I produce 1500rpm. I'll need more torque down there (even though there's already plenty)

sorry this thread is a month old, but, i just wanted to point out that an i-6 without a muffler sounds like a tractor and also that i cut off my muffler and had 2.5" piping run from the cat all the way out the back to a 3" tip and it actually increased it by about 2mpgs.

edit:: i have the 5.2L V8

My major experience with driving without an exhaust system involved the S10 I had when I was in college. The original catalytic converter had given up the ghost, so my roommate and I drilled holes into it until I could get it replaced. You could literally hear it a mile away, and the lack of backpressure pretty much removed most of the already-meager low-end torque from that wheezy little Cavalier lump. When I finally did get it fixed, some half-assed welding and clamping meant that the joint on the back end of the replacement cat hand to be held together with hose clamps and cans after a short while. Needless to say, I'd find myself driving with open headers. Again, same loss of basic driveability.

Minimal exhaust backpressure is really only desireable in high-rpm turbo applications. Driving like a sane person on public roads pretty much rules that out. I think, however, the loss of FE from an open exhaust comes more from unconsciously trying to compensate for the low-end power loss while driving.

wow, i see alot of BS with this subject

first of all, your factory pipes are crush bent, just because there is no ripples, does not mean its not crush bent

second of all, exhausts can help MPG, but it mostly depends on the car & how bad the stock exhaust is to begin with, & how you drive

i work at the only tri-state area mandrel bending exhaust shop, I know a few things about exhaust

www.mandrelbend.com is our website

There's a company that makes aftermarket turbo kits that install way down the exhaust system; they pull the muffler and let the turbo serve that function. The noise is about the same. They skip the intercooler, too: ten feet of turbo pipe dumps a fair amount of heat from the compressed charge.
