So I'm Pimping out the rear section of my twin exhaust from the axle back by sending it to either side of the ute.

Q: As I'm removing the rear muffler, what/how many mufflers should I use to make it quiet again, preferably quieter. (space constrained)

- 2x of the oval mufflers have the same internal volume as the existing twin muffler so would that produce the same sound output?
- Or I could fit twice as many hot dogs. How many hot dogs would it take for equal silencing as one oval muffler?
- Do these 2 types work the same or differently?

I don't know the sciences of mufflers other than I want straight through unrestricted pipes, no baffles or 1" Varex chokers thank you.

 

 

 

Current setup is venom 4" dump & Cat into Pacemaker twin 2.5". While it sounds nice I want it to go louder with some sort of bi-modal/valve setup as I leave home in the mornings while the family is still asleep.

 

Plan is unbolt the rear section above the axle & go from there, running one pipe straight up under the tray and through the rear tailgate. The other one will go up and across just behind the diff then out the opposite side of the tray, both straight pipe.

Trick is once they get up under the tray ill put a y-pipe & butterfly valve to a 2nd (& 4th) pipe running on the other side of the trays main beams which will be full of mufflers for silence.

 

Ill be moving the reversing lights, get half size break/blinkers & re-route some wiring. Also try & go Quad 4" tips but may have to settle for Quad 3.5"

 

Between toolbox-Beam I have 5" tight so 4" wide mufflers at a maximum.

What ever you do, don't get xforce gear. They are pretty loud.

What size tips are they Masda? ^^^^

Ummmm, ummmm NFI. Let me walk outside for you...

 

There you go mate

3.5" tips

Magnaflow for the win.

I've got unbranded magnaflows on my xy and they're loud as now after 1000 miles. They were really good when new. 

gee that looks like a lot of stuffing around man

 

just dump it at the diff

Nope don't even think about dumping at the diff if you want to keep your hearing after driving 20 minutes, was a headache after that long with one muffler.

you can still have 2 mufflers around the diff

 

doesnt have to just have 1 ya know

 

a forum member did something like this but only to one side. *beep* of a job to get right to avoid knocks/noises etc.

Ive had the rear section unbolted for a couple days and there's no way I'd be able to put up with the noise all the time, I need it to go quiet.

Plus I'm mostly doing this because I want the Big quad tips through the tray look
