well i have started getting tired of the droning on my 4" straight pipe system[65 to 75 mph]. i am fixing to put in a resonator or a muffler. when i have a heavy load, it is too loud in the cab to talk. mike

 

Is there some way to go inbetween stock muffler and no muffler? A guy around the corner has an '03 without a muffler. When he gets on it the windows shake. I would like free flowing but can't subject my customers to that kinda noise. Sure can hear the turbo tho... ;D

 

you can get a freeflowing muffler like a magnaflow or something simalar

Wait... Wait... Did he say &quot;Bad Donkey&quot; Have to use that one ;D ;D .<br> Wheels

 

when i first did my straight pipe i used pipe that was a little over 3/8&quot; in wall thickness (dad is a welder hence it wasn't thin exhaust pipe). it seemed like it pushed the drone up to around 2700rpms (hard to tell when the motor was stock and barely able to hit that rpm). thicker pipe does change the resonance and therefore the drone shouldn't be ~2000rpms where it's annoying. <br><br>Tom<br><br>btw, i don't know of any shop around here that'll do straight pipe, espcially when there's a cat on there.

 

I got one of these ultraflow welded mufflers put on .......<br><br><br><br>http://www.dynomax.com/ultrafloweld.stm<br><br><br>not really any louder than stock, no drone, and I still got the faster spool up and reduced egt's out of the deal<br><br>I wish it was a bit louder though

 

Just thinking out loud here...What if? What if you did put a glass-pack in place of the stock muffler? ??? Like I said, Just thinking out loud here.....But also looking for a answer too..

 

Is everyone removing the muffler only or both muffler and resonator? Thanks

 

A shop here where I live suggested installing a 3&quot; x 30 Glass Pack. Does anybody have any information on doing this?
