New exhaust... Opinions please. :)

I just bought one of these....

Holden Commodore VZ V6 Sedan Pex Sports Exhaust - eBay Mufflers, Exhausts, Car Parts, Accessories, Cars, Bikes, Boats. (end time 28-Jul-09 17:33:10 AEST)

Do you think it will increase performance? Im also looking for something relatively quiet... Do you guys reckon this will fit the bill? *flame suit on*

would be interested to know how easy it is to install and what kinda improvements you see

[Danoz]

Sure mate, I will keep you informed. It should arrive and be installed next week.

yea would be good a video as well! good luck!

I will try and organise that too. I did always think that dual 2.25 into single 2.5 inch would be the optimum for a 175 Alloytec...

Honestly, at $300 i wouldn't expect much performance out of it.
Will probably make a bit of noise tho being straight though mufflers, also might have a bit of drone on the high way.
I have fitted a similar exhaust to this to a mates vz, very easy to do (1 hour job)
It gave a sporty sound under hard acceleration, but that's about all it did.
Have noticed it gets quite hot at the bends too.

Important tip! Go to Super Cheap Auto and get yourself a tube of exhaust cement. Also get some new flange gaskets. Don't make the same mistake I did, get a good seal first go!

I have the same sized system on my 175kw alloytec and its awsome not much performance but to get more kw's out of and exhaust you'll need to do alot more like intake, cams and tune but i find its a really good system, I only have the middle muffler on mine and i also have pacemaker headers, I dont get any drone on the highways and its nice and crackley too

Good buy mate

The first thing I see wrong with it is that in the description they say the system utilises the X pipe design. No it doesn't. No where in that system is anything that remotely resembles an X pipe.

As FAT.36 says, it doesn't give any performance improvement. The reason is that it is restrictive. Twin 2 1/4" into single 2 1/2" doesn't work. Especially if you have extractors. The improvement in torque with extractors is totally lost in the system that is too small.

Most people have found that the alloytec loves to breathe, even a twin 2 1/2" is better than that system....IMO.

That's my 2 cents if it matters.

I think they have just cut and pasted a description from another item... I would think that anything larger than standard would be an improvement. Anyhoo, the proof is in the pudding.. Video and audio coming soon.
