Hey Guys,

Would it be worth while changing my exhaust to a twin 2.5" with an X-Pipe - would it give me more power? or should i leave it as a single 3"? I've already got High Flows and extractors.

Cheers,

Hey Dude,

It hasnt been dyno tuned, just a generic tune but the Sniper box was $495 and the Tune file cost me $195. If you want a custom dyno tune it will cost you $495 for the Box $395 for custom tuning and $120 an hour for dyno time, so about two hours to tune it, maybe 3 hours. It made a big difference doing just the generic tune tho. I wouldnt get the dyno tune tho until you have all the bolt ons, as it will need to be re-tuned for every other mod you put on after its tuned.

Havent run it down the quarter since it was stock aye, but might be this week. Will let ya know when i do.

Cheers for the response dude! Yeah somtimes its not worth the expense aye, If it was holding back like 20KW i would do it though. Only prob is theres no way to tell until you get it done, or know someone with an identical car and the same mods.

Hehehe that's the way!! :). Yeah that is about right aye, i reckon once i have under drives and a custom tune it will be there.

Speaking of under drives, did your power steering get heavier? Mine sometimes shudders as it is now, could do with a fluid change tho hehehe. And alot of people say it damages your engine, but i don't see how.
