Hammer Down

I tried to get a decent take off but it's the street so the traction was not very good but enjoy. You will have to turn your head or your mobile device as my videographer didn't film it correctly. ��

Sounds beast!

Elhonaz

So you did the "gutted" thing?

Dublinoh

Took me back to the Steve McQueen movie "Bullet" when the Charger starts the chase (arguably the best in moviedom). Awesome LOL, did you set off alarms or scare any little children?

Hammer Down

We bypassed the u bend that goes into the main chamber so that the air flow goes straight into the first chamber and out through the two pipes that exit the muffler. In a stock muffler the sound gets muffled twice. This mod will cause it to only be muffled once. The sound is not only louder it's deeper than stock (SL55ish) I wanted to increase the sound without changing the M113 tone.

Here's more of a steady soundtrack

Never raced, only pampered


That's the beast in its natural habitat right there!

its funny that you say that because after my little smoke show my wife says "what was that a baby burn out" I replied "I'm not one of those guys that will lay rubber down for 200ft" (thats a waist of tire )

Did you happen to get any pics of the inside of the muffler?

Hammer Down

Here ya go

lol...i can hear traction kicking in well into second gear.

Hammer Down

Yea the old traction control likes to fight when I get on it up to about 100

Forgive me, but after looking at the pictures, I'm still not clear on what you did to mod it.

Hammer Down

Where the exhaust goes into the muffler it goes into a u bend that is inside the main muffler. We cut off the tube that sends the air to the u and welded a metal circular piece to block off the entry and the exit of the u and cut down the two extended pipes in the front chamber. The air now flows from the inlet of the muffler out the twin perforated pipes inside the main muffler. The sound is now only muffled once.

Awesome. Thank you.

Here is the finished internal (I assume).. I got this pic from another thread. Any drone after you implemented this setup ? How Close is it or Better than a C63 sound ?

HeissRod

Holy crap. Those welds and cuts are terrible. lol

TheTherapist

This totally makes sense. Always been hesitant to gut the muffler and dubious about pulling half the guts out in an attempt to try and avoid that raw raspy edge, but here's the solution right here. Cheers Hammer.

dyno

is it still a solid unit after all the opening, cutting and re-welding job ?

ben73

Can anyone who has done this comment on the drone at 60mph?
My car has the mufflers eliminated and it's terrible.
I am going to reinstall them, but will consider doing this mod beforehand if it does not result in a drone at highway speeds.
THANKS.

The greatest engine noise of all time, I often watch it on Youtube just to remind myself.

Island_Moose

Is there a thread that details how the muffler is modified?

oneslow55

Sorry ,but that's pure shoemaker work ,do it right and get c63 mufflers best tone you'll get

Hammer Down

I've changed that set up and gone to a sound not even the C63 mufflers can produce.

oneslow55

C63 with long tubes and a resonator sounds better and more exotic.Your setup is very raspy ..
