I dont really mind noise myslef I used to have a cammed ss that was heaps louder than any xr6 ive heard, is the 4" really loud or it would just be loud for some people? Also I was on your website before how come the 3.5" system is heaps more expensive than the 4"? Cheers Scott.

Its just louder then most poeple like. Yeah prices vary due to manufacturing costs more so than size.

I've got the full 4" on my manual sedan...have had it for maybe nine months now.

I also went for the single humungo rear muffler. It's a bloody tight fit and is a little

loud sometimes on longer highway runs..gets a bit tiring, but man it sounds good when you're

up it and on over run..

I plan on doing the F6 turbo switcheroo pretty soon, so went big from the get go..

OK, so compared to a defillipo or similar the quality isn't the same, but a good

economical option I rexkon.

Cheers

Deano..

yeah that's wat im thinkin for the price why would you pass it up.

I have just had the X-Force system put on my car. Stainless Steel all over, 4" Dump, 3.5" hi flow cat, daul 2.5" pipes at the rear. Also added a growler cold air system. Power went up 64RWKW! Much more than anyone had anticipated. The noise of the system is incredible. Not overly loud, next to nil drone on cruising speeds, but brilliant burble and flow on acceleration.

Highly recommended, what prices have you been quoted?

Do xforce make 4" system for ba/bf for $1400?

the rear craddles are the same and the floor pans are similar I have wondered this too, I'm putting a fg exhaust manifold on my ba soon and I'll be using a fg 4inch dump to so will be finding out if it mates up to my x force ba system
