Default n/a downpipe question

If you had to choose between mandrel bent 3" and 2.5" for an L36, even if it could potentially be 240 whp, which would you choose and why?

I would say 2.5" since hp is directly related to flow and there is no way that 240 whp can out flow a 3" DP.

Am I crazy or what?

I would suggest 2.5 as well. There is some torque lost when you upgrade to 3"

2.5" hands down. I can't really justify it. Just feels right.

2.5 all the way. I can't imagine an L36 outflowing a 2.5, even with 240 at the wheels.

No plans. It'* just a debate I can't win outside of this forum.

only reason for a 3inch DP on a L36 is if there is a turbo sitting between the downpipe and motor because at that point the back pressure doesn't matter much
