How to tell if GruppeM is authentic?

Hey guys,

How do you tell if a GruppeM exhaust is authentic or not? Thanks,

If it makes more power than the stock air box? I kid, i kid.

I'm sure there's a badge of authenticity stamped on those things.

Sorry thought it was the intake.

honestly if you can see it in real life you should be able to tell just by the quality of the carbon/kevlar work as the knockoff will be junk.

One way to tell is a metal plate riveted to the front of the intake with their logo and a serial number.

If you talking exhaust check the Serial Number if its 05-0116 its the replica model.
I have seen Gruppem Exhausts with diffrent numbers.
Take care.

Not in all cases is this true..

Search, There is a thread noting all the differences. Serials #'s, Welds, Weight, Ect.

Regardless of what you end up with they sound the same. Replica VS Original. Weigh almost exactly the same. I believe the Replica was 1-2lbs heavier. Just be ready for it to be loud.

Yes, I meant exhaust. So there is no definite way to tell through pictures since I am most likely buying one from the forum online?
