You can shoot them an email to see if they have any other videos. You could also search youtube, maybe there is one on there without the SC. :cool:

Someone interested in a group buy should start/gather a list of names of people willing to purchase this exhaust, contact each person via PM to make sure they still want to purchase it, and then approach Greddy as a group ready to purchase so details can be worked out :cool:

Why even start a GB for the Greddy system when the JOE Z true dual exhaust system is already available and affordable. let's poll how many ISF owners are running the JOE Z system and what their feedback is. I personally have been experiencing the system for about two weeks and am truly pleased!

The JOE Z system is way less than 2K. What is it about the Greddy that has such appeal? The JOE Z sounds great fits perfect weighs less and delivers dyno proven HP and TQ improvements of 22-24 and 15-18. Can you get more out of an after market exhaust system?
