guy im just about to get a s/s exorst on mye ca18det ute im running standard turbo and running the maddat dump pipe now was size pipe should i use? 2.5 or 3 or ????

next over or under the diff

this is a weekend / drag / fun

neva gonna see a speed hump or curb

I would say 3" is the way to go.
As for it passing the diff, over here in QLD it has to go over the diff. In my sunny the 3" pipe was a bit of a squeeze getting it to clear everything as it's nearly 3 times the size of the original

this is not going over the pits and if it did i would swap the exorst has its goin to be stainless steal tig welded and very loud... no way i would cut it to put in a nother muffuler for the coppas

so you would go 3 inch and under the diff ?

Yeah, I would go 3" bacause forced induction engines dont need back pressure the same as n/a engines do. So i have been told.
And if it doesn't need to be legal then go under the diff, as it will flow better if you dont have to put a big half-round bend in the pipe to go over ther diff.
Or just finish it before the diff with a little dumpy tip or something.

im runing a high mount t3 turbo and my zorst that were making only has like 3 tiny bends one at the back of the turbo 90. . then one bout a foot down where the firewall bends in thats around 40d anda bend to send it strait under the ute all the wayout to under the diff and one 45 degree up to me cannon. . not sure on under over diff legaly here in nsw but stuffem lol

Would someone please explain the difference between an exhaust and exhorst .....Many Thanks..

same thing i cant spell sorry about the mix up

dw mate docroc is just to dumb to figger out the real word we all got what u were sayn . .

haha laney and perthute you seem to have your hands in each others pockets and the same spelling capacity

3" & over the diff for me.......
Nothing to do with the law.... I figured I'd be more likely to be dropping the diff out & having the 'zorst over the diff means 1 less thing to unbolt.
So far my decision seems to be well founded.... I've had the diff out 1/2 dozen times for various reasons & haven't had to touch the exhaust.
