Outer Limits 4x4 Board

HI ALL just thinking of removing the muffler from my 3" exhaust anyone done it and got away with it. Ive got patrol 2.8 and its not that loud with a straight through turbo muffler just after more noise and NM`s

Too noisy brother...the boys will follow you everywhere...putting a straight through hotdog in there will fix that problem though!

hrmmm
thought the turbo acted as a muffler?

I got a mate runnin a DTS kit without a muffler and its not LOUD LOUD.. but if he puts the boot down.. u can hear it..

Thank`s I was thinking that its just when the shop was fitting the exhaust I heard them moving the patrol out of the shop with only new 3" bend on the turbo that replaced the cast bend and it sounded sooooo good turbo whissling it`s arse off but no louder than those rice burners

Definatly do it. I had straight through 2-1/4 inch pipe from turbo back on my surf and it wasn't crazy loud. The three inch diameter will flow more but i still think it'll be fine... It'll whistle very nicely.
Worst comes to worst you can always get a resonator put back in where the muffler was.
And yes GQ you're right, in a way the turbo acts as a muffler, but only by breaking down the individual pulses of the motor into more of a flowing sound.

My 2.8 turbo lux has a 2 1/2" system with a single straight thru muffler and its a lil loud.

Do you think it should cost under 50bucks It`s only a foot of pipe

Hopefully, I used to worl for a Midas store who sold it for $65 a metre. A bit rich I think but you should get it cheap enough

Ive got a mate running straight thru on a 75 series Turbo 2H no mufflers!
Crosses across behind the tray, about 4inch pipe!
LOUD! But sounds sweet as! Ask rocknferoza!

i ran straight through on my lwb 3.3 td and was great, but using exactly the same exhaust on my swb it was to loud (only 2' of pipe shorter). Put in a short straight through resonator, and quitened it down just enough, and made no noticable difference to performance.

i had my muffler off ... it was a nice note and whislted like mad
was hell loud tho! cause it was dumped straight to the road and echo'd
now i've got a hot dog in to keep it quietish .. till i open it right up

I put a 2 1/2" straight pipe on a TD4.2 T and it was NZ legal and was not
unpleasent to drive.
Now ran the LT1 thru the same system and it sounded sweet but was cop bait so we fitted a Supa Flow muffler.

Carts of the board has turbo 2h in his 60 and his muffler fell off one day offroading and he liked the sound of it so he got a straight through part made up from a exhaust shop in castle hill industrial area for 20bucks he bloted it in and it sounds awesome, however he found it a bit loud inside so he has his muffler back in now but always has the option if he wants to unblot and throw in the straight through if hes in the mood every so often

sounds like a semi-trailor though its so nice

mate has a turboed 1hz in a 75 that's ripped the exaust off basically from the turb back, sounds quiet enough untill he opens it up under load... then it's a little roary... but at least something drowns out the simex's. don't know how much boost he runs, but gives HSV clubbies a run for the money, and outdrags 350 chev powered cruisers up hills

ur in sutho shire so give the boys at sutherland exhaust a call.... Matthew hunt is the owner and hes pritty kewl and ive had ll my cars exhausts done there and all my mates go there too... them or menai mufflers should giva ya a good deal .. $50 i paid for a straight through end on the vn and the vk i had.

I had my old MQ with SD33T. Straight thru 2/5 inch sounded pretty damn good.

i got turbs on my 2.8 lux, its got 3" pipe from back of turbo and a small turbo muffler its only bout 1.5 metres long (the exhaust that is not the muffler) and it sounds like a mack truck, its got a good sound and its louad wen i get up it. i also ran it 4 a while wif no muffler and it didnt sounds as good as it does wif the muffler.

Sound`s like the best thing is to get flang`s welded each side of muffler and existing pipe than straight through pipe also with flange`s than I have both. I had a 253 dunny door with 65mm pipe and extrators done at sutho which sounded sweet and a vr dunny with 65mm and extractors done by menai mufflers which was ok for v6. Ile have a word to sutho tomoro about price

Does a turbo diesel need a muffler?
No of course not, but any gain in hp would be marginal anyway, if anything it will just make cool wirring and hissing noises.

Do the police and RTA think you need a muffler on your turbo diesel?
I dont know, drive past one at full pace and see what they think.

RTA inspector lives 3 houses up from where i park for work every day im sure ile find out as he has been spoted with tape checking head light hights and looking at my non existent swaw bares

Next time get a tape out and start measuring him up to see how he likes it! If he asks you what your doin, tell him your working out what size box you will need to get for him!

Called in to sutho exhaust about half an hour ago the guy said nup straight out he`s not putting his arse on the line and every car must have a muffler to get rego even turbo diesels that are quiet with no muffler.

Just fit a straight thru resonator. Removes the Boom and still sound smooth.

If you can hear it, it must be fu(king loud!!!

its only loud at 2200rpm and just off idle but I want to piss the neighbours at 6am when go to work

We had the D series Ford Turbo trucks over here with no mufflers.
I thought they came that way from the factory but it's a bit long ago to remember.
A 6 will always be quieter than a 4 through more firing pulse's.

Pfft, do it yourself then, or get a mate to do it.... If you can be stuffed driving all the way to my place on a weekend i'll weld it up for ya. What a crock of shit, as if he hasn't done heaps of dodgy shit on ricers by now.

And you wonder why the RTA inspector keeps measuring the truck up!
