Guest Guests Posted 29/09/04 11:52 AM Share Posted 29/09/04 11:52 AM Just got back from Carline. They took off the rear muffler to let me have an idea what it would be like. Faaark!!! Sounded unreal. Floor the peddle and the car roared to life, lift off and quickly down through the gears with the a beautiful symphony of pop's and burbles from the rear end. Back on Saturday to have the thing removed and a straight 3" shoved in. Just hope it doesn't drown with the pipe in place.Anyone know how to post an audio file. Most folks found,,,leave the rear,,,remove the centre muff,,,is the way to go...But a 3" system,who knowsThey reckon Brockie came up with one pipe for V8s,and it gave more power.who knowsvik Link to comment https://www.fordxr6turbo.com/forum/topic/13124-3-exhaust/page/2/#findComment-170574 Share on other sites More sharing options...

I forgot to reply hence the sorry. Link to comment https://www.fordxr6turbo.com/forum/topic/13124-3-exhaust/page/2/#findComment-170615 Share on other sites More sharing options...

Jim Member 12 Member For: 22y 3m Location: Lara, Vic Posted 30/09/04 05:51 AM Share Posted 30/09/04 05:51 AM Just measured the internal pipe size of my zorst which was 60mm.60+60=120mm...has to be better than one 80mm pipe I would have thought???but that's just me vikI just went through some of my fluid mechanics books again (and got myself a bit confused) but the basic reason behind a big single pipe flowing more than a double one is that the flow through the pipe is not uniform. It is slower at the pipe surface and fastest in the middle. A double pipe has more pipe surface than a single pipe of the same cross section, so the double one has more slower moving gas and therefore less flow.I hope that's not too confusing. Man, you should see the equations they use to calculate this stuff!!

Guest Guests Posted 05/10/04 05:24 PM Share Posted 05/10/04 05:24 PM you all miss the big picture cross sectional area is important so is less surface area and most important is the fact that your not spliting 1 3' tube witha restrictive divider into 2 tubes at the cat Link to comment https://www.fordxr6turbo.com/forum/topic/13124-3-exhaust/page/2/#findComment-172979 Share on other sites More sharing options...
