I know sounds like a stupid idea but I wanna know if any one has done it, dont go crazy at me as this is the only way

I could find out

get the centre muffler removed as well as the rear but keep the hotdogs that are before the rear muffler an put

a milo tin on it? got no mods to my car as I just wont a nice beefy note

I have a stock system that has no mufflers at all, this is for off road use only.

its really really loud way above legal and is not advisable for street use.

yer!! do you think having them hotdogs an muffler would change it? I have a ute so its the twin 2 1/2 inch or wat ever it is standard

im not sure about the ute, the rear muffler on a sedan is the main noise reducer.

its louder with no rear muffler and the stock centre muffler in place, with no centre muffler and twin 3 inch hotdogs at the rear its real loud and hetrodines like a loud 300zx.

you need a balance pipe before the twin hotties to remove this strange tone.

you should be happy with centre muffler removal only its not too loud, im using a berklea centre muffler and twin 3 inch hotdogs at the rear and it sounds nice also has a 5 inch cat and 4 inch pipe off the cat to a custom splitter.

We've done a few of these as custom jobs, but with twin cannons... not too loud really.

Would removal of both mufflers create less back pressure, thus effecting torque? Or is the main restriction the CAT here? Getting my centre muffler removed, and whole section made up with just stock pipes, and when ringing around was advised by one work shop to remove the rear muffler too and just have straight pipes everywhere. When I asked if this would be too loud, they said "no"

Think about it mate, mufflers are there to reduce noise. No mufflers = very noisey & droney.

Buy a cat-back system or just remove the centre muffler to start with if it's a different note you're after. If it's performance, stick a hi-flow cat in & the note will become deeper as well as an added bonus

Also best to confirm then, when my straight pipes for centre muffler area go in on Friday, will it DECREASE performance due to backpressure? I don't need to get my car-retuned right? Currently 265rwkw on 10psi

Do you have a hi-flow cat installed at present? If you do, I'd chuck it on a dyno to check AFR's after centre muffler is taken out.

No, it should not decrease performance... In saying that, its not going to dramatically increase flow or power so a retune isnt needed.

Through to center muffler, the pipe diameter actually goes down to 1 and 3/4 inches as opposed to the 2 and 1/4 inches for the rest of the catback, so you should decrease backpressure.

You will notice that your exhaust will burble and pop a lot more too. Iv read that this usually goes away if the vehicle is retuned!
