Your website only shows a catback?
GHL shut down for about 6 months at the beginning of the year for 'restructuring'. During this time they stopped production of their products. last i heard (end of july) they still weren't making downpipes yet, but were making cat backs again. this would be why only cat backs are shown.
a buddy of mine has the 3" non res GHL and it sounds pretty damn good. a couple of complaints he has is 1-the ghl dp has no hanger and 2- the rear section of the exhaust only has a hanger on the drivers side (the last one before the tips)...this causes the tips to 'twist' when you step on it.
regardless, the system is pretty awesome.
i have the eurojet tbe system, and i don't have any complaints about it. it's def not as loud as the ghl, but when you go full throttle it opens up a lot. everyone i know says it sounds really throaty and mean (particularly compared to the resonated ghl system). the eurojet system has dp hangers and has the long hanger rod to reach the pass. side of the car in the rear, but eurojet doesn't offer a non-resonated option at this time.
we will both be in ocean city this weekend if you want to hear them both.
