Originally posted by blown1500 Brad Perry, if you call the mans. they will usually give you the numbers. Ratchet, I use the stock manifolds and mufflers for stock Mercruiser, HP manifolds with mufflers for Mercruiser with elbow, and approximate the tubing size for the headers used. Wet exhaust is like mufflers. Hope this helps. Remember, the 2000 is a good tool for changes, just close for absolute numbers. |
