Default TWE Header Question

Okay I have read the few threads that have specifically delt with the TWE header. However, my question is that should I get the super stock or high output. Some have mentioned that the super stock is not worth getting, and that the high output one is better. When I get the header (not a question of if, but when) I plan to put on a track pipe, so I am wondering if the high output will be too big with the track pipe. I plan on getting some of the TWE cams and a Perrin lightweight pulley later, and currently I have a cold air intake and catback for power mods. I am looking for some opinions and hopefully more people who have TWEs will post than in the past. Please tell all

From TWE website:

This Super Stock exhaust system is designed for the customer with a mildly modified engine and boasts all the features listed above. The header primary tubes are 1.625" in diameter and the collector outlet and remaining piping is 2.25" diameter. *The 'features listed above' are a header, cat section, midpipe, and muffler.*

"This High Output exhaust system is designed for the customer with a highly modified engine including an increased engine rpm limit and an upgraded computer engine management system. The header primary tubes have a shorter tuned length for high rpm power and are increased in size to 1.75" in diameter. The collector outlet and remaining piping is also larger, measuring 2.5" in diameter."

So if you aren't going to increase your rpm limit and upgrade your computer engine management system, go with super stock. This is what TWE recommends.
