I removed my muffler (not resonator) and installed a stainless exhaust pipe that TOTALLY fits the size and shape of the SRT-6 rear end. There is no resonance and the radio works fine without getting that BIG DRONE of most exhaust modifcations. I get lots of positive comments and it is NOT loud until I really get on it and it starts to get up on the cam / supercharger and then it is a HIGH $ sounding european sedan sound that is really nice, others words not mine. THe pipe is from Summit racing for a Diesel and is a twin 4" polished stainless setup. I cut and TIGed the pipe as shown in the photos attached if they upload. Click on them for a larger view. Also see my LSD installation for the rear end, Woody.

Seems that I have been educated a bit, the resonator was not removed, the muffler was. THe muffler was full of stuff and I will add a picture below to show the amount of junk inside of it, LOTS of fiber material and baffels. I first tried to open the MUFFLER and gut it but when I replaced it it did not sound any different. There may be a slight increase in power but my G meter was not used to see a difference before I started. The rich sound is nice and not loud inside, at normal highway speeds you have to try and notice an increase. When you firewall it the sound is quite nice, even better than my 6 pack 440 challenger and your hearing would say that it runs stronger. You can not go on the seat of the pants responce feel as it is less accurate. NOW the SPRINT BOOSTER is a real kick in the pants especially when you are on the track autocrossing and that is good for a second or two in a 45 second lap, its well worth it.

PS the pipes are even with the rear bumper from a top view. The curved body makes then look like they protrude a great deal. The sound levels in the car are even normal because the sound pressure waves do not interact with the bodywork and cause resonance, like my Challenger exhaust tips (1973 style) Woody Northern Va area.

I now have the video of a run on the autocross track on You tube so you can hear the car without the muffler, look up Autocrossing my SRT-6 Crossfire in Maryland. 1/24/2008

 

Wow, that thing you removed was the resonator? I always thought that was the muffler. Shows how much I know.

 

Look at the layout of the pipes and see that the last part has been removed and replaced with the Y pipe. The lump that you see is the AMG stock muffler and is a HEAVY piece. Click to see detail(s), woody.

 

nice can we get some sound clips

 

Is that what is called a "catback"?

 

I am 99.9% sure that you removed the muffler and kept the resonator.
The resonator is the big silver box w/AMG stamped on it. The muffler was at the back w/the tailpipes that is stamped 'Sebring.'
Nice bottle of Beefeater, that's my choice of gin as well.

 

First off woody, where in Virginia are you located?

Second, I'm VERY confused at the moment. I think there must be some disagreement here on which part is the resonator...

The section that you replaced is refered to as the Rear Muffler in the service manual. The section that everyone else I know of has replaced is the Large Trapazoid section that has two pipes going in and one coming out. It's labled AMG on the bottom of it. That is what is refered to as the "resonator." I wonder if the sound is much different depending on which section you pull out. I think the what I have referred to as the resonator is a bigger restriction than the rear muffler.

Here's an EXCELLENT How-To on removing what most of us consider to be the resonator:

Yup. He removed the muffler, not the resonator.

Looks like you got rid of the muffer. Good work, but personally I think the pipes are a little too low and stick out a tad much. Post some clips if you get the chance.

 

Might sound pretty decent!

 

If all the Resonator removal does is make it sound better with little if any HP increase, then removing this muffler may be a more cost effective and easier solution to better sound...

Sounds Clips?

 

I think it looks good and is very different - quality part used - would love to hear a clip of you going down the road has the sc does not engage when reving in park or nuetral.

Good work. Nice to see something different yet quality.

 

I as well can not wait to hear the sound of your crossfire. Did you intent to remove the resonator and accidentally remove the muffler thinking it was the resonator. lol This time it just might work out in your favor I cant wait I hope it sounds better then with the muffler left on and the resonator removed.

 

Why can't someone just make a direct replacement already that I can buy, cut out resonator(not muffler like OP), and clamp in with some high quality clamps? Am I missing something or can someone direct me to where the item in question exists?

 

NeedsWings was working on one last time I talked to him. Not sure what the status is at this point.

 

Curious to hear as well, but I'm willing to bet that it sounds raspy and a bit too loud for a classy vehicle. There are some videos on U Tube that show some Xfires with mufflers removed. Heck, even with some straight through mufflers, the car sounded like a Tuner Honda. Not my cup of tea.

Hope you and the cat enjoyed the Gin !
