Whats A Good Muffler?

[DRIFTPIG]

Im after a good free flowing muffler for my r33gtst. Its way too loud as it is and needs to be quieter quickly!! Is there any good types of mufflers that flow freely and also cut down the noise dramatically? I dont really want to go the route of puttin 2 mufflers on if i can help it. Just dont want cops pullin me over cause i dont think they would appreciate what it takes to get 280rwkw as much as we appreciate it!! lol

Basically if i get done by epa/cops.....There will be one less skyline on the roads for a HELL of a long time!!

What is everyone else runnin here that has reasonably quiet cars?

i think the key is a nice big resonator before the muffler...

sometimes you jsut have to bite the bullet and sacrifice a few kW's for the sake of being road-legal...

hmmmm, "sacrifice kw", its not a term i'm too familiar with!! lol

yeah i think you may be right on this one.

i'd be surprised if a resonator would take off more than 4 or 5kW and this kind of power difference is the same as any discrepancy between dyno's anyway...

on my last car I had a resonator fitted to drecrease the noise...and to be honest it didn't make much difference...I believe you need to source a good quality jap muffler eg: HKS, fujitsubo etc...I think it has something to do with the amount of baffle it has...so I was told..those cheap and nasty chrome cannon mufflers are normally loud.

yeah its got a jap rear cannon and just put a good 3" muffler half way along, that lasted bout 3 days, got it dyno tuned, pumped 20psi into her and blew the shit outta the muffler!!! Waste of $180!!!! Thats why this time i think i'll hunt around first and check out what others are runnin. The thing that doesn't help me is:

*4" mandrel piping

* No cat, just casing to look like it

* No resonator

So basically i'm relying on 1 muffler to do all the work for me! Its also runnin a 45mm hks external gate with screamer so if i do want it loud i just gotta give it a pisslin!! Shit this is gettin annoying!! WHAT TO DO??!!??

lol no wonder it's loud.

Get the hugest mid muffler you can find .. whack that in and see how you go. Also put in a cat. It's not worth the performance vs hurting the environment/getting reemed.

I would be suprised if you noticed ANY difference other than a noise reduction.

[DRIFTPIG]

Puttin a cat back in, i'll notice the difference all right! lol

if ya ever get bored go to an exhaust joint and have a look at a good condition cat, they are so restrictive its a joke!
