Resonator removal ?

Good evening people,
I purchased my GomanGo charger #3912 just over a week ago and love it!! I am a bit disappointed with the mellow sound, even though the Daytona supposedly sports a "performance exhaust". I am considering removing the resonators, and trying it for a month. If that doesn't do it, I'll probably put some flowmaster 40s in. Has anyone removed just the resonators, and if so - did you like the result??

Thanks,
Brad

Re: Resonator removal ?

Firstly, welcome to the board Brad! Glad to have you with us! We're all a bunch of nuts here, hope you'll enjoy it.

There are a bunch of threads here that cover both removal of the suitcase, as well as resonator removal, and even more covering various complete aftermarket Cat-Back kits. As for the "Performance Exhaust", it actually is, as the front muffler (the suitcase) is a straight-through design. In other words it is not baffled.

If I were you, I would start with removing the suitcase first, instead of the resonators if you are in any way concerned about interior resonant noise. This is the method I coined a name for called the "Brylcreem Exhaust Mod". Check my sig for a link to the thread about it. It's very cheap (most places are less than $60 total bill), boasts a pretty decent boost to the exhaust note under load, and is easy to revert to stock should you choose to.

Resonator removal - If you don't care about interior resonant noise (drone), and want a substantially louder exhaust note, then this is a great way to go. It will cost you either slightly over the Brylcreem method, or potentially alot more, depending on what options you choose. You could replace the resonators with glasspacks or Flowmasters, which will keep the sound pretty subdued, or you could just have some new tips and pipe welded onto the hanging pipe after the resos have been cut off. This will yeild the most noise without going to a fully straight-pipe setup.

Both of these options, or even a modified Brylcreem setup where instead of replacing the suitcase with short pipes you mount a Flowmaster or other muffler(s), are all going to be relatively inexpensive compared to going with a full Cat-Back system.

To be quite honest, the performance gains are going to be pretty close accross the board, as these cars already breathe very well. You might see a slight increased yeild in HP from the resonator delete as they remain the most restrictive devices after the cats.

I'm sure others will post here too and give advice! Good luck with your choice!

Oh, and btw....post some pics! It's a requirement here

Re: Resonator removal ?

I want to say THANKS!! to RTjunkie for his timely response, and due to that response I have started down the "MOD" path on my Charger. Of course - being in Southern California, they tried to charge me 150 bucks for the change. I got them down to 100 and went for it. Sounds more like a Hemi now!

Thanks again,
Brad

Re: Resonator removal ?

I removed my Reso's, and love it, replaced those HUGE heavy puppies with a straight pipe. I won't put anything back on untill I trade it in for a Challenger.
Yes there is drone at any thing over 2000 RPM, I just turn the radio up to around 25 or more and I can't hear the drone at all!

For those that like to lighten the ass end of the car, reso. delete is the way to go. I can smoke 'em with less energy = less gas... See I am helping the enviroment! I can also slide the ass end of my Charger around a corner much better now.

Re: Resonator removal ?

Heh, I am still giving serious thought to deleting my reso's. I've already killed off the Suitcase, can you imagine the roar with the reso's gone!


And yeah, which mod did you decide on Brad?

Re: Resonator removal ?

I had the suitcase removed, and an really happy with the throaty response now. One of my friends commented this past weekend on how quiet the exhaust was, and we just can't have that!!

Re: Resonator removal ?

I went the reso - delete route, I've heard one with no muffler and resos left in place and it wasn't as agressive (still sounded good, just not as agressive...). Had mine done for $150, but the tips were $45 a piece (3.5" diameter x 13" long, polished stainless). Good example for the sound, check the "leavin my mark" link in my signature.
