Does anyone have any insight into the significant cost difference between GMG's headers at 4400 and Fabspeeds at 3000...?

They both have 200 cell cats and seem to be the same material and diameter.

My impressions of both brands are that they are 'equals'.

Any ideas or thoughts here?

Honestly if you're going to do headers or a system for this, I would HIGHLY recommend Kline and have them do an inconel system for the car. I wouldn't mess with RS headers unless you're replacing with a really really really well done piece of equal length kit. It's one of the things porsche does best bar NONE otherwise and you pretty much only stand to lose power...


And no I'm not a dealer and I don't work with them at all. But I have some Kline pieces coming for my turbo s (headers back) and for the Huracan (just exhaust).The rep for the US is EPICLY great with customer service too which helps. (Sam at By Design Automotive in LA if anyone is wondering)

Thanks. Where in PA are you? I'm in Collegeville/Skippack.

These would be for a 2016 GT3. I'm looking primarily for more of a race car sound. Gaining power would be awesome, but I'm realistic here. But I certainly don't want to LOSE power.

Dyno on GMG look very good. Better low end & top end. Equal length and 200 cell.

Did Fabspeed Side Muffler delete with valves, great sound and you save 35-40 lbs.

After some research I'm good to go.

Stay tuned for my official decision announcement

Ran Fabspeed Headers, 200 cell cats, and free flow muffler on an '03 C4S. The headers are equal length, F1 collection technology.
The GMG and FVD products seems very good and race proven based on websites and RL comments, but the Fabspeed technology and shop is state of the art.
At this time my GT3 is still stock, contemplating exhaust options.
Good Luck.
