price?
Any plans of taking that car to the track? I'm so tempted to buy an E55 now that the aftermarket has improved greatly
Want to see what my MBH longtube headers make on a stock 55K?

Very Nice! This is why I've always said that if I ever decide to mod my car I will address the exhaust 1st. You add hp without touching the engine. On average a pulley and tune would get you about 50hp &50ftlb's with added heat. I know that these headers are expensive but I believe/know that they are worth every penny. Hmmm 125mph traps with a stock engine and exhaust mods only????

Very nice gains! I have one question; why do you prefer 1 3/4" primaries over maching the 55 S/C ports at 1 9/16 or 1 5/8 primary size? Larger primary tube diameters, than the exhaust port can decrease exhaust velocity exiting the heads.. Again, huge power gains but there might be more on the table still.
