Congratulations, you've found the most well made, high engineered, best performing, and most reliable HFC's for the G37!

As requested, this is the official group buy for our G37 high flow metallic catalytic converters. These are true high performance catalytic converters that are SMOG legal in 49 states and are OBDII compliant.

They feature full stainless steel construction from tip to tail, thick warp free flanges, high end 99.99% pure electronic grade copper gaskets, & complete hardware kit. The HFC's are turn key, nothing more is needed.

Please do not procrastinate, we will not be giving this pricing out again.

UPDATE March 8, 2008:

RAIN CHECKS! Our stock levels are running low on some of the components that go into the HFC's. Starting today this GB will be on a rain check only basis. Those of you who place your orders after today (03/08/08), your HFC's will ship on or about April 21, 08. Also note that there has been a slight pricing adjustment to the GB price as well as our standard web store pricing. My cost on stainless sheet has gone up from our last run, as well another price hike from Magnaflow/CarSound for the cats.

lazy i believe there are some gains.. some1 hit auto 1/4 mile 13.5 And he is going back for more runs he said he could have done better. He also ran with an intake which reduced power. So ima say the berks carried his run. So w these installed he told us that he can do better then 13.5

I think the BERK cats dyno shows like 8-10HP gain and I think maybe 7TQ.

On the VQ35HR on 07-up G35 sedan, you'll see 7-8 rwhp, + 10+ ft/lbs of torque. This is with pee water 91 octane. For those of you who have 93 at the pump, you'll see even more.

For you G37 coupe owners with the stroked VQ37HR motor, you should see ~2 more HP and at least 2-3 more ft/lbs of torque. So until I actually test a vehicle, I'll tenatively put the G37 coupe at 9-10 HP, & 12-13 ft/lbs, at the wheel.
