After a lot of set backs i,m neally ready for pipes for my BB.Only ones i can find are tri y,s.Just would like to know how they perform on a stroked 460 now 488 up to around 6800 RPM.
I believe that the tri y are suitable for lower end torque, however you dont need to wory about low end torque when you have 488 cubes. 4 into 1 would be more suitable for 6800rpm.

I just used a set from www.castleauto.com.au on a 502stroker in an XW with edelbrock aluminium heads.It sees a max of 6000. They are tight out of the head and could be better,but they did fit in the car nice.
Yes i would preffer 4 into 1,s but I can,t seem to find any off the shelf to fit a XW & custom pipes are around 1500 to 2000 to have made.A bit much money for me right now. I will have to go with a set from castleauto thanks Greg.Hey Greg just wondering if you used a c4 or c6 & if you had to alter the crossmember.
Thanks Dale.
I picked up another 600 revs by changing from tri y's to a 4 into 1, but I'm talking 6400 to 7000 rpm
for what an off the shelf set are going to cost you, hold off if you can and get a custom set made, it will be cheaper to do it now rather than replace the tri y's later on

Yer I hear what your saying ratter but it,s getting harder to hide the expense from the cook.Had to purchase a few more things than had planned [solid roller and assorted fruit to go with it] thought better to do internals properly .So for now tri-y,s , might be able to cut ends & weld a collector on.
I actually used an FMX behind the 502..I cut the ends off the tri-y's and had them pumped up to 3".I had to tidy up the pipes inside the collectors a bit.Had 3" flanges welded on and a full dual 3" system fitted.
