Open Manifolds: Y-pipe or Short Dual
Disclaimer: Pure Stock dirt car
When I add my L98 manifolds to my basically stock motor, I'm going to have to redo the short pieces of pipe on the car now. Ive been debating on just running a short piece of pipe from each manifold and dumping under the car, or actually running them into a Y and out the passenger side.
With such low hp levels, would there even be any benefit one way or the other? Im thinking not, but would like to hear other opinions. Keeping each pipe separate would be a lot easier.

i'd make a Y, with both pipes close to the same length if at all possible to help with midrange scavenging.

true. May have to wait until I swap to an automatic then to make sure I have clearance.
thanks for the input. May be easy to incorporate, not sure.
