nat_daly · 06-08-2005, 05:03 PM

im sure for pre 83 cars its 94-96? and for cars made after that its been dropped to 90 now.

you could just say stuff it and whenever you see a cop push in the clutch and idle past hehehe.

Did he win the Golden Muffler Award (tm) too?

nat_daly · 06-08-2005, 06:40 PM

has he removed the muffler?

FordFan86 · 06-08-2005, 07:01 PM

His coupe run's (12's?) on avgas and drowned out my stereo up fairly loud while overtaking someone 3 cars ahead of me.... ing LOUD! He runs a twin system with 2 mufflers and that's it a i think. He said it was a fairly straight exhaust system so the gases didn't really get slowed down... i'm sure he can tell you more about it than i can.

90dB at 3000 rpm(?)

It doesn't take much above the stock system, that's for sure. I got my system done on my BA with the proviso that it had a decent bark across the rev range but didn't scream when I stuck the boot in. Been into a few booze buses then and not raised an eyebrow.

Exhaust noise has been cracked down heavily in Sydney recently. When I had my system done, there were several cars in there getting theirs reworked after a defect notice for too much noise.

What has rich got to do with anything?, its about doing it right, that means if you cant afford it now just save a bit longer.

nat_daly · 07-08-2005, 04:21 PM

but apparently taking the muffler off and replacing it with stright pipe, ireduces backpressure helping the engine function better.. how is it not doing it right? if this is the case?

benXaGt · 07-08-2005, 04:38 PM

Mate you should here mine then in my coupe i cant cluch in past coppers i have to turn the car off and roll past them :p

Nah seriously but i have a 351 xa coupe running pacemaker extractors and 3inch 2 pipes into 1 pipe into a hotdog and exiting out the left side of the car no muffler and i run it every day i think im going deaf lol.

Its not legal but i havnt been told off yet :P

nat_daly · 07-08-2005, 04:42 PM

man thats what i like to hear! lol my mates got a 351 XY pretty good car for a p plater.. lol
yeah but you love the sound of your car right? u wouldnt get bored of it..no matter how loud it is..
cheers,
Nat D

Citric GT · 07-08-2005, 04:55 PM

I'm contemplating removing my one and only muffler too. All that will be left is the resonator at the back.

I decided not to worry about the noise regulation because if all those habibs can get around with 100+db exhausts on Honda Civics, I should be able to in a sweet Windsor...

benXaGt · 07-08-2005, 04:58 PM

hahahaha sik yeah i had a 351 xa sedan when i was a P'plater and it had 3' straight through exhaust system with lukey mufflers you could hear me coming like 3-4 kms away same as my coupe really. Yeah i love the sound of a V8 nothing beats it. No way id get bored of it why do you think i bought another 1 cause there ace. The manual is way better sounding then my old c4 auto. Btw just dont draw attn to your car and the coppers wont hassle you out.

nat_daly · 07-08-2005, 04:59 PM

ahh good someone agrees, and yeah your right you see riceburners with 5 inch tips running way out of the legal range.. the way i see it $70 for a louder car and more throttle response is a cheaper alternative

benXaGt · 07-08-2005, 05:10 PM

So what car do you have?

Yeah ive owned 2 cars now and im 21 years old a xa sedan and a xa coupe both 351's the coupe im paying of and the sedan i still own but i gave it to my brother in law for $2000 i spent about $8000 on the driveline and it handles really well it can take corners at like 70/80km/h and has no body roll but it got yellowed and taken off the road.

nat_daly · 07-08-2005, 05:16 PM

this is dissapointing but i only got an 1999 au falcon ..until i can afford a decent XB!!

so i want to make it as tough as i can but while not hurting the bank budget too much
you should of sold that to me!!! $2000 now thats a bargain for a 351

benXaGt · 07-08-2005, 05:20 PM

Yeah i no i had the engine all recond and the gearbox recond 1yr ago and new suspention nolethane all round, big fat tyres, flat black paint job , it was a very evil car and turned heads everywhere even though it was roughf on the outside. I miss it heaps but got a better toy now

nat_daly · 07-08-2005, 05:24 PM

benXaGt · 07-08-2005, 05:25 PM
