I agree that the Kleemans are very similar. Actually, I never knew how easy it was to have a set fabbed and how many people in San Diego that have spent many years on race exhausts. I was initially very against cutting the primary cats but have now relented. i just don't see the Kleeman setup as a very good compromise for two reasons. First, and foremost, i really don't know that you can get that extra 20 or so HP going from shorties to the Kleeman mid sized and you still have to cut and weld. Second, why pay the price when i can have a custom set made local for less?
If you go custom make sure the use 304 stainless. You also want a true collector not miter cut primary pipes. Use mild steel for the flanges. 1/2" thick if possible.

2. supercharger engagement is no different than any other car. harsh engagement is a byproduct of a larger crank pulley and/or s/c clutch. since i had my s/c clutch replaced with the improved version, engagement is dramatically improved.
3. ZERO gas fumes unless i'm standing right behind the tailpipe.

Drone was a poor choice of words, exhaust noise is a better term. Other long tube cars I've driven in have had significantly more cabin noise from the long tubes. Maybe the E55s extra insulation/etc helps?
It is not merely a biproduct of a larger crank pulley and/or s/c clutch. I felt a significant difference in supercharger engagement going from the LET tune to the VRP tune I had now. The harshness is effected by a number of things beyond just the mechanical parts - how the engine makes power and where it picks it up will also effect the "shock" felt when the s/c engages. If you are saying yours has not changed, I find that surprising.
I assumed that if Jangy were to add long tubes he would not have catalytic converters, you do have cats.

i do agree there are more things that affect s/c engagement, but my point is that headers are insignificant compared to these other things. without changing anything else, my car went from very abrupt engagement to better than when it was stock just by upgrading the s/c clutch assembly.
you could be right about an exhaust smell with no cats...but the exhaust is carried out past the end of the car so i don't see how that would be a problem under "normal" driving.

headers
I have been debating long and short tube headers but can't justify the price tag of any of these tuners. There is no reason why headers should cost over 1000.
I would say try to get with a good muffler fab place and have them custom a set for you. You should be able to get long tubes made for around 1000-1500K
