Close enough for government work for sure

The 41021 has more volume than the 41029 but less than 41030

The different shapes of headers create different pulse wave escape/return effects , some work well with some pipes ,some work well with some engines and some you just don't wanna use ;)

The exhaust length, shape and all that hoopla is a deeeeeeeeep conversation fershur , do some research ;) :lol:

When i did a rough measurement for comparison only the 41005 measured approx 3.00" and my RB 192 was 3.30". This was inside flange to flange along the centerline.

Its all about how they perform , you can sit here and theorize forevver but on track testing is much more pertinent ;)

Watch the government comments Monty.. someones always watching.

The older P5 you worked on is ready to race. The freshing up really did the trick. Hoping to break in the new P5xlt this weekend. Thank you for your superior service and sharing your knowledge.
