muffler advice

[wildturkey]

a new law change and all of a sudden my cars too loud! WOF man told me might not pass next wof. I'm runnin 3" straight off the downpipe out to what I have been told is quite a small cannon style muffler.....could be the source of my probs? Is it just a case of upgrading to bigger cannon to deaden the sound? What should I look for in a good muffler anyway? any advice appreciated

i think normally the crappyer your muffler the louder your car?

i.e trademe mufflers are louder than say - rps, hks mufflers

i dont how size effects the muffling, in threoy bigger muffler means more muffling?

: Yes the bigger the muffler the better it "muffles" wildturkey best bet would be to get a 2.5 RPS muffler...no not the cannon type its a straight through muffler around twice the size of a cannon, and won't restrict flow.

Here a link. I got one put on as a removable type and got through a WOF

Weird. Go to lower hutt pitstop and talk to them about it. Should cost you $400 fully installed.

$400??? im sure you could quiten it up for cheaper than that (even if its only for W.O.Fs)

[wildturkey]

ouch!! 4 hundy?

Maiden Mufflers in Upper did mine (they stock RPS) rear section for about $300.

To quieten it down you need to put resinators in the mid section... They have a variety their and are top dudes, They know there stuff and explain it all to you . Say your from ClubSub, and you come recommended from the guy with the blue STI wagon that he did last month (he should remember)..

He did my mid section with resinators and tail pipe.

The noise also depends on the type of down pipe you are running - 3" is louder than 2.5", same goes for mid and end section.

[BC5RA]

$400 would be with a flange made up so you can remove it and put your cannon back on.

Obviously there are cheaper ways but no one asked for the cheapest way to quieten it down did they.

[funkytown]

No - i had mine made up with flange and pipe etc..

[wildturkey]

sweet appreciate the advice its all good. What about the ones adertised on TM?.....I have seen them with bolt on inserts that are supposed to deaden the sound. Anyone got one of these?.......and pass a wof with 1?

Okay, well you got a better deal good for you champ :

[funkytown]

Law states that bungs have to be welded in to pass a WOF - In practice, it depends where you go for your WOF,

My RPS cannon came with a bung at no extra cost..

Failing all else - I have a complete V7 STI standard bolt on rear section that will make your car fly through a warrant (its for sale).

Be your cheapest option to fix the problem

[wildturkey]

and it would bolt straight up to my 3" for how much?

[funkytown]

It was bolted up to my 3" midsection prior to me changing it all to 2.5" midsection with a resinator, and RPS cannon.

If your in Wellington cum round and try it, Il flick it to ya for $75 how does that sound?

[G-unit]

i have a full 2.5inch from aftermarket down pipe with 2 coby mufflers in the middle into 4.5ich cannon,91db witout silencer in

[wildturkey]

yeah I'm in L hutt. message me ur cell

[wildturkey]

cheers G but my preference is for a straight thru system with no doglegs or cobys interupting flow. If I can get that and quieten my sound for 75 slides that's me all ova

[G-unit]

same but car came with them fitted so yea no point removen them, also could try muffler shop for a silencer 2 be made, mates 6inch silencer was 90buks and thats in a small town,should be cheaper in a city, trade me sell cheap cannons with silencers also

[wildturkey]

yeah I seen those ones........big arse Powerpro ones with silencers. Only problem is that the silencer apparently has to be welded in permanently for a warrant. I wana try avoid that if I can because those silencers must surely restrict the flow. Would rather have a quieter free flowing muffler at the back without having to put in resonators

[G-unit]

na local guy sells different 1s, never had 2 put silencer in for wof so wouldnt know if they have 2 be welded in,will ask bro in law when he comes over,hes a mechanick
