that's how a muffler reduces noise, by restricting the exhaust flow. Therefore, the ascending pistons meet more pressure in attempting to push the exhaust gas out, sapping power. <img src="/forums/images/graemlins/kewl.gif" alt="" /> True but IIRC not enough back pressure also saps power. Not sure why though since race vehicles often run very short pipes. Perhaps it's a torque thing or a hp vs rpm thing. <img src="/forums/images/graemlins/confused.gif" alt="" /> Anyhow I have the same problem I use 3 band clamps to hold it in place. I haven't had time to drill it out and use a nut and bolt yet but I think that will be my next course of action. <img src="/forums/images/graemlins/kewl.gif" alt="" />

I think there's more to it that just a need for back pressure. This explains it better than I can <img src="/forums/images/graemlins/kewl.gif" alt="" />

I guess I forgot to mention that it's still stock pipe up to my gutted cat, then a 2 1/4 pipe from then on. I agree with it being a little more free reving but I didn't really notice a loss of power or gain for that fact.......

$1.65, and it's fixed. <img src="/forums/images/graemlins/smile.gif" alt="" /> I'm happy. There is a bracket/hanger thing near where the pipe goes over the rear axle that is broken. I intend to rig something up to relieve some of the stress that is on those bolts now. I know that bracket got broken when I was rear ended a few weeks ago. <img src="/forums/images/graemlins/frown.gif" alt="" />

LOL Did you really use C-clamps? <img src="/forums/images/graemlins/smile.gif" alt="" /> It was a pain to get the old bolts out, just because my tool selection is limited. I ground the old ones down, and then used about 5 different bits, in progressively different sizes, until I could hit it out with a punch/hammer. I'm not sure what I'm going to do where that bracket broke off. I should probably see if I can find someone to weld it back up for me.
When I have to get a new muffler, I'd like to try one of those magna's. How about uploading a sound clip so I can hear it? <img src="/forums/images/graemlins/smile.gif" alt="" />

Damn straight! Add up all the time you spent with those bits... I took me about maybe two minutes to put the c-clapms on. I admit that every couple of months I had to retighten them. But what the heck, it was easy to do, and easy to know when- every time it started getting a little bit louder than usual.
$Free.99 repair that lasted until I sold it and had to take the time to do what you have.
Having said that, you shouldn't have to jack around later now like I did...
