I have a gtech, my car has run 5.3's to 60 mph and also gained 30 rwhp through different exhaust setups on a standard engine. Sure it's a 304 but the theory is the same. I've gone from 9.4 1/8th miles on the standard exhaust, to 9.2 on a 2.5 inch cat back, to 9.0 on long headers into twin cats into 2.5 single. To..... who knows but +15rwhp on a full dual system that finally has let the headers to there job and is by far the biggest gain I've have had from any of those systems, I know exactly what gains came from what system (it's had 4 different exhaust setups on it so far) and I have no doubt it's still alot quicker straight out of the headers (which are 38 inches long with 8 inch collectors).

You can do the same on the V6, but you need good headers first a good merge to help scavange the collectors and then whatever gets it out to atmospheric pressure with the least restriction possible. The point I was trying to make is that all your gains on the exhaust are from the header/collector and your merge after that nothing matters so long as it has the least restriction possible. All race exhausts end at that point

I have a 2003 VY Storm Ute. At the moment it has a stock exhaust system (single cat running one pipe through two mufflers).

I was going to just cut out the end muffler and put it straight through (or a resi depending on what would sound better), but the piping from the cat-back has some rust on it so figured I should replace it. I don't want to spend much as I only want the sound and can't afford extractors and a new cat.

A Redback system would be nice but I can't justify the cost just for some sound. Would it be possible to install a 2nd hand SS setup (most of the ones Ive seen are dual pipes)? I dont want to install hotdogs as I would prefer to not look like a d!ckhead.

Yes the SS set up fits but you need to get the twin cats to suit. Zeussy has done this mod. Should PM him.

I ended up taking out the rear muffler and putting a pipe there instead. Cost $100 at the local exhaust shop. Now sounds a little more like it looks.

Thanks to the straight up talk above me I realised I was never going to get a power increase with a cat-back so what's the point.

What type of exhaust do you suggest Holdencommodorevp? and how much would this magic exhaust cost, and why would you bother on a stock standard V6, a 2.5 system is high flow, a straight through muffer, it will still gain power but not much, even extractors on a v6 doesnt do much either, at the end of the day there is only so much you can do to a v6 and paying out the ass for **** you dont need is pointless, a 2.5inch exhaust can flow 150rwkw dunno how meny N/A V6 buicks out there with that.

So, I'm looking at getting a brand new exhaust to replace my shitty old standard one on my V6 Vn Calais... Now I dont want something REALLY LOUD.. but not quiet either, something that will turn heads and still make an amazing tune.

I've had a quick talk to the local Rev 'eds and the best suggestion of come up with so far is: a 2 1/2 inch pipe from CAT back with one muffler and 1 hot dog with a chromed tip.. which should cost between $300-$400 from dynoflo in dubbo..

any suggestions would be great.
