Yep i will certainly be going dual 2.5". The headers on my 200kw dont look to bad, they are not as pinched as the ones were on my Au.el2xr8 said:Mate you know what I'm gonna say don't ya..
FULL DUAL EXHAUST IS THE ONLY WAY!!! :thumbup:
Don't compromise. Get a good set of stainless coated headers (same size as mine, too big have adverse affects), and a decent set of mufflers, and throw away the rear resonators. Make it 2.5" dual all the way and you will be in aural heaven.
As I mentioned b4........ Whats wrong with a single 3"svo302 said:Ahemmmmmm
Whats wrong with single systems???? As far as i know single systems provide an even better scavenging effect due to the pulses being in a single pipe, straight from a custom performance exhaust joint that did my 3", looked good on the dyno also, gained heaps more power with a minimal loss in torque.. I can live with that.. Jeff Garland in belmont YOU R A WIZARD
Hi SVO... I think a single 3" is fine for all the mods you have done to your car.!!!! but most people dont do anywhere nearly as many mods.svo302 said:

Back to the bottom I go lol
A single 3in on a blown 6 would be restrictive letalone on a v8....XR8chic said:

When I get my baby supercharged I am getting a single 3"
You gotta remember too that an exhaust system is always a compromise. Sure you could go bigger than a 3inch, but it could be at the expense of some bottom end. Same thing applies to headers bigger equals more top end at the expense of bottom end.Martin said:

Interesting. I wonder if X-pipe at 2.5 inch dual would be better than a balance pipe setup?XR9UTE said:The reason Fords like dual exhausts is because of the firing order basically. You have more exhaust pulses per bank per 180deg of firing than say a "boat anchor" engine.
A dual 2 1/2" with balance pipe is generally better on a Ford.
If you use a 3" tailpipe with a dual 2 1/2" ahead of it, it is actually much the same thing as dual all the way due to the fact that after the mufflers the pulses become less important to the scavenging effect.
I went from a 3" mandrel single on my 351w to a compression bend 2 1/2" dual and picked up 15hp and 24lb /ft torque.
From the tests Ive seen there doesn't appear to be much in it.Aussie Pete said:
