Quietening Exhaust

[Borci88]

Hey guys,

I've currently got an X-Force turbo back exhaust system which is 3" from turbo to cat and 3.5" from the cat onwards. The only muffler is the one at the rear. I want to get a new muffler welded in and I was wondering what I should be looking for as I'd like it to flow as much as possible without it effecting performance TOO much. I also want it to be fairly quiet at idle and even when driving around normally but still want to hear that RB note when pushing it, any ideas on what muffler I should be looking at?

Cheers,

Borci88

Any decent quality, locally supplied large bodied straight through mid-muffler would do the trick.

same story here, except mine is 3.5 from turbo, with one rear muffler and a 4" cannon. Any idea how much a mid mounted muffler would affect performance? Kinda don't want to sound like i'm racing every time i pull away from the lights.

Any decent sized muffler that is straight through, will be fine.

And don't get a Varex. They are illegal in Victoria so will cause more problems than they will fix.

Damnnnnn nismoid,they don't leave you guys alone down there aye

You can obviously get defected up here if they figure it out and the decibels are too high on open but they aren't illegal..

Trust PEII will solve your problems

Im currently looking into the same thing myself.

Have an HKS hi power that is far too loud with a 3076, so have borrowed a Trust PEII for the time being. Am making up a new center section consisting of a large 3.5inch straight through oval muffler, that i will run on the street, and replace it with the HKS center section on the track.

Without intentionally hijacking the thread, do any of you aussies know about therse mufflers?

M&H Muffler. The only 3.5inch i can find

I just swapped over my Fujitsubo cannon for a 12 x 8 x 18 inch straight through di fillippo muffler. Still got the rb sound but quietened it up a lot and would barely affect flow if at all. Absolutely love it.

I spoke to Racepace and that was there advice get the biggest straight through quality muffler/s you can fit.

I've read people complain about the X-Force Varex being a restriction even with the butterfly open, swapping it out with a different muffler and gaining power

[Borci88]

Maybe so but in my case it's not a Varex, just a standard X-Force system with I think a 4 or 4.5" cannon.

Keep adding straight through large oval bodied mufflers until it is the volume you desire.

Look into Magnaflow Race series oval mufflers.. they do 3.5 and 4" straight though all stainless.

I have a 4"one..
