Hum???

 

if he is selling what is posted on the pic, you already know he's a fat BSer. Thats a pretty big and obvious OBX stamped on the exhaust there but he is claiming its an Apexi??? how weird.....

 

what brand it is i still dont' believe..

how they might have come up with thsoe numbers

1 tested the car with a full exhaust system (intake, throttle body, ported intake manifold, bored out exhaust, ex manifold, y pipe, test pipe, cat back and stock muffler) then they slap the new one on.
so the muffler might increase that many more horse with but would require all other mods.. since the muffle might be just he last bottle kneck

another method is they stick it on a turbo car.

 

that picture of the muffler looks like it was been tampered with. it looks like something was erased all along the ride side of it. it's a scheme, yo. can't truss it! no no no no
