Soon im going to bet getting a new exhaust for my LC with a 202.
The only mods i have got on it so far is a 350 holley.
Ive sot some extractors to put on.
Now should i go for a 2.25" or a 2.5" syatem?
What set up has everyone got? (size and muffler)
Should i go for a lukey or any other brand of muffler.
Cheers

I'm running a 2" on the stock 173 I have. Orginaly I had a 2 1/4" exhuast on it, and it was good at high revs, but a little boggy down low. With he 2" there is a big difference in low down torque around 1800RPM.

Fair enough mate. There were other factors to my car being boggy (like the 2.78 diff cause it was a factory auto), but i will still stick to my opinion of 2" on stock Holden 6s.Just a thought mate, things dont always come out wel over the net, but i mean no disrespect.
CHEERS Chris
I'm planning to keep the 2" even when I put the hot 202 in.

I don't care if the car goes better or worse, so long as its sounds FAT
It had a 2" with centre 12" hotdog and single outlet muffler. New high compression engine fixed that one up, every time I gave it a bootful it looked like a cat had crawled up the exhaust and was being blown out piece by piece. Bye bye muffler
Cheers,
Craig.

But with the webers, port/head work, cam etc.... mine needs to breath a bit more than a stock 202...

we dont recomend Lukey mufflers
Why? I have just fitted one and would be interested in your feedback as you obviously have experience in this area. I'm sure it would also help others.
I have used Redback mufflers on my XR8 and they rusted out inside two years, but maybe a bad batch? The car wasn't used very often (5000kms/year) so I understand consistent low exhaust temps could have contributed to this.
Thanks,
Craig.

I wanted to get the XU1 type look with the duel outlets. Bigger is not always better. I have tripple CD carbs, 10+ comp, worked YT head with rollers, big wade cam and found that 2 1/4 was the perfect size exhaust.gtrtorana, your system sounds pretty much the same as mine, except for the dual outlet muffler

These "................" that want lots of noise.....music to their ears, yada, yada......cant they just have the throttle connected to the volume on their ipod with their favourite v8 symphony ....so the noise is loudest inside their head and nowhere else?

It includes a muffler and resonator.
The car also has extractors.
The reason I chose this setup was it offers good flow and would probably meet RWC noise limits.
Your problem would be fitting this system under your car.
Mrs RoDoMo was able to hear me coming from 2klms away.
Now I can sneak up on her

Its now heaps more drivable of idle and the power is more noticable lower in the revs. Also heaps louder than the old setup
