Muffler only

[greesie]

Hey guys
Had abit of a search around but couldnt find a thread that had what I wanna no.
I'm looking at changing the muffler over, and only the muffler for now anyway,
And was wondering has anyone done this? Like does it sound good/bad, make any difference to performance etc?

Thanks for the help!

what engine?

i did it on the ZD30 engine. big change in performance. looking at the stock muffler its not surprising as it has a very narrow neck at the start of the muffler.

 

[greesie]

Yeah mate it's a zd30,
Ah sweet did it make much difference in note too?

Cheers for reply

 

[greesie]

Haha just quickly aswell was it 2.75" or 3" and roughly how much did ya pay? Might go get a few quotes this arvo,

Cheers again

 

[tweak'e]

note- depends entirely on what, if any, muffler you fit. mine does, its not quite the muffler i wanted but i also had to keep it quiet for work reasons.

Hey greesie, let us know how you go. Are you gonna put a different muffler or just straight pipe?
Cheers

 

[greesie]

I don't no yet, just gonna get quotes may as well get quoted on both, will chuck em up.
Rekon it'd be too loud straight pipe? Maybe a hot dog or resonator or something?
It's only a fine if you have no cat isn't it? Like having no mufflers would only be yellow stickerable?

Tweake wont agree with me but I personally think the dump pipe is the most restrictive part.

 

[greesie]

Yeah I thought the dump pipe was, I'm chasing abit more noise aswell, so though the muffler will help with that and when I can afford I will do the dump pipe, also thought the muffler would be cheaper than doing a dump pipe

 

[Dave]

Hey Greesie.

Pm me your details, I promised you the dump pipe I have.

Decided to keep the one thats on the Nav.

The other one is brand new. Just needs a pyro plug welded in.

 

[tweak'e]

mines 2.5" to keep noise and cost down.

and yes i disagree with Dave
the muffler change is the best performance for the $$.

 

[greesie]

Haha cheers mate, I'll have a think about what to do
