My 300C looks mean and tough. On a race track, it tears up the competition.
The Volant CAI has a sweet 'big V8' induction sound.

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.

The headers will make the burble at idle so much better. Deeper and louder. I put the borla 140125 on my magnum and thought the idle was fairly nice. Once i put the headers on, it sounded like a real v8 muscle car. and the power, OH THE POWER!!! +35 horses is an awesome feel.

Sounds like I'm gonna have to try it! I've seen reference to the "Reactive" tips on other posts, anyone know where to see them?? :burnout:

Here are some pics from today(click to enlarge):

Where can I find those exhaust tips?
Almost every speed / aftermarket shop sells Ractive tips. Autozone; etc.
These are a round, rolled tip made from T304 Stainless Steel with the Ractive Logo on the top side - Here's a link to the Manufacturer

T621 - The tip is comprised of T-304 stainless steel and features the Ractive signature polished mirror finish.


T621 - 4 INCH RSR STYLE SLANT CUT TIP


Hope this helps.

hey NR, thats for great idea! this is definatly a great alternative to purchasing an extire exhaust setup.
i stopped by my local Monroe today and after the guys there were done gawking at my car, we put it up on the lift and i showed them what i wanted done (as you explained). said they would do it 'off the clock' for about $60 which is definatly a helluve deal.....although ill prolly give em a lil more just for being so helpful.

so if im correct, you removed the 2 resonators that are at the rear of the car by the bumper entirely? we were discussing removing the 'suitcase' that is in the middle of the chasis instead of the 2 rear resonators.....what would happen if we removed that? although ill probably stick with just removing the 2 rear resonators like you did. also what are the 360 clamps you purchased, and what exactly do they do? im unfamiliar with this exhaust stuff, and want to know the advantages of having them, versus whatever else they would use?

i also plan to swap out my 300C bumper, with a base model bumper so i do not have the exhaust cutouts. then im going to add some 4" rectangular tips, much like those on Camaros. i think itll really give the back a clean look, and add to that muscle car look. let me know what u guys think!


(thanks again for the idea NR!)

Yep, the resonators by the back bumper.

If you also take off the suitcase mufflers in the middle you'll have no sound quieting and no back pressure. You need to leave them or replace them with tuned mufflers designed for the 300C.

Have fun!

Heard of others doing this mod & having drone problems at around 2000rpms, sounds like you don't have this, the only problem I've with this setup is that it looks cheap, & I guess it is, comparing to the full kit, For me, I love the look of the Magna-flows, & once I get the Headers it will sound even better. To each its own, I'm not knocking you, just my 2 cents, & as long as your happy with it,that's what counts. :banana:

Gee, I never thought of that.

Hard to see under there when I'm driving.

Next time I run someone over, though, I'll ask them if they thought my system looked cheap (after calling 911, of course - I'm not a complete Neanderthal). :biggrin:

Not quite. Camera was a foot off the ground. Seriously, I know where you're coming from, Cruznit.

You like the chrome look on the mufflers. I like the black out look. I usually paint the pipes and cans flat black with Hi-temp paint. I probably do that this weekend.

Now that's what I'm talking about, didn't think of that :sly: , I think that will do it for me too :biggrin: , were I was coming from was like, you know people,they go behind your ride checking it out & they see the nice looking tips & they say, Damn!! Those are some BadA** looking headers, then they crouch a bit to look under and :wtf1:, get my drift. All in all your ride looks damn good!!! :headbang:
