Inexpensive Exhaust Modification

[Northern Rider]

If you modify the exhaust system it will only affect the part of your warranty regarding the exhaust system.

There's just one problem. My exhaust sounds like a deville in a funeral procession.

Quiet. Stone cold silent. I can't stand it any more!

Following the lead of a few other members, i took the plunge last week. My black beauty went up on the hoist. The 2 big rear resonators were surgically extracted. Two straight pipes were pressure bent to shape. Then 2 reactive 4" tips were welded in place.

Lowered the hoist. Everyone from the muffer shop standing, waiting, listening. Fired her up. A sweet, deep, bump bu de bump bu de bump bu de burble issued out the back pipes. A big v8 awakening from a sleep. Gotta love that sound!

Blip the throttle - stand back - a menacing growl spits out - echoing through the work bays.

They all want to hear it on the road under full power. I circle the back streets and pass by the shop along the main road. Wot -serious power; kick-butt acceleration - and a sound that has jumped from the flames of hell.

I circle back to see a bunch of midas monkeys with silly grins on their greasy faces.

Job done.

Yeah, they're happy, but will it pass the wifey test? Friday, we head out on a 1000 mile round trip to a family gathering. I start up inside my garage. No comment. Roll out with mild acceleration - some exhaust note - again no comment. 20 minutes later, i pull out to pass an 18 wheeler - 3/4 throttle. The beast jumps forward with a roar. After the pass, my wife says, "boy, does this car ever move!"

the car is still quiet at cruising - a distant exhaust note but no drone or resonance. No difference when going into 4 cylinder mode. No more comments about the sound - but she is used to me having noisy cars in the past.

Lots of positive comments from my relatives - especially the burble on idle.

I am happy with this inexpensive mod. Even if i go to a "tuned" system such as borla or zoomers, the resonators would have to come off.

Will i go to a fully tuned system? I'm not sure. Once a good chip programmer is out there and we can see some dyno numbers - i would go to a full system and headers - if a significant power boost is to be found.

was this on a stock exhaust? Want to get a more gressive sound too but not over the top

Will removing the resonators effect passing inspection?

Removing the resonators has nothing to do with inspection at all. It will not affect it in anyway. The only thing that resonators do is control or limit sound that comes from the exhaust specifically drone noise to the interior of the cab.

Pulling resonators off an SRT8 = good sound

Pulling resonators off a 5.7L with MDS = DRONE!!!

I see that alot of people do it and seems like a good mod just for sound. Could u use the stock tips or go with 4" tips?

I'm thinking about removing my resonators on my 05 5.7. What do you mean it sounds like a drone? Does it sound bad?

Yes it does sound bad. After listening to that drone on a 500 mile trip, you would rather have your head in an elephant's butt, while it farts!!!!

Personally I don't notice a drone but then I usually have music playing on long trips. I have an audio clip on the previous page, post#167 that will let you hear mine. Hope it helps.

^^^This.

I barely hear any drone. But I normally have my radio on.
Even at average volume I dont hear any drone.
If the radio is off and I'm cruising at 60 or so, I can hear a little but it's not annoying to me.
Actually I like it. Lets me know I hav a beast under the hood...
