Default Difillipo Big Boy

What are the specs on the Difillipo Big Boy system? it doesn't have it on their website anywhere.

Is it a full twin 3-inch?

What would be the cost of it?

And how would it compare to a custom made twin 3" stainless system with quad outlets for a ute?

it is twin 3 inch then single 3.5 over the irs cradle, back to twin 3.

This far back in the system you dont lose any flow - at least up to 500rwkw

I made 18rwkw extra with the big boy and BPR cold air, compared to a previous full custom system and YT cold air, that was 2.5inch though

The headers are longer tube 1 7/8 primaries with a trick little cinch for the right backflow from the 3 inch collector

I've already got the Difillipo 1 7/8" primary headers, and some ballistic 100cpsi cats, was just interested in the cat back, but for a ute seeing as i don't have to worry about IRS, is there a separate system for the ute?

No seperate system, its the same as tweeked has described above unless you want quad outlets.
Go ahead and do it, I never got tired of the noise on my old BF ute....my neighbours hated it
