The Pro's have Merge Collectors and a better "X" pipe plus metal matrix CATs if I remember correctly. Merge collectors are more work to fabricate as is the "X" pipe.

The street will be fine if you are planning only to do minimal other mods to your engine. If you are planning to do lots more engine work then the pros would be more appropriate. The difference on mildly modified motors is minimal and the streets will be sufficient, maybe a 5hp difference, does not justify the $700 difference. Hope you ordered in time to get the extra $100 off. BTW, this is what I was told by the folks at LGM.

Had the streets installed on my '04 vert about 1 month ago...I couldn't justify the added expense for the 5 - 10 hp difference. Use the money you save on a good Tune!!

My sentiments exactly, I can accomplish alot more for the $700 spent elsewhere. My car is 99% a street car, I doubt I'll feel 5 hp in my seat. BTW, an additional feature of the streets is that they come with the entire exhaust system and headers fully polished, whereas the pros do not.
