funny watching the Ford guys sneaking a peek under the car
The really can sound different
and we thought helped torque off the corner and we could make the exit pipes smaller for ground clerance

I bought 4-2-1 collectors with race bullets at a swap meet off a sprint car header. Tried those sounded nice but no noticable gain from standard 4-1 collectors. Then I used my 4-1 collectors and put longer pipes on that exit by the rear wheels with a 3" x pipe. It changed the sound of the motor completely. Sounds like I'm reving it to 10K when I'm only shifting at 6500. It sounds really cool and people are always asking about it, but again it was a minimal if nothing on track gain. Obviously it changed something with the tone of the engine but why no results in et? I was wondering what is causing the change. An older guy asked me if I had 180deg headers on my car? Never heard of it but he says thats how they sounded years ago.

makes it sound like
an engine that actually has a 180 crank
this makes it a little easier to set up the 180 headers for high rpm use
