firstly i want to say hello as im new to scoobynet
right i want to know if my HKS silent hi-performance zaust is genuine, it doesn't say HKS muffler on the back box like some of the pics ive seen of them but it came with a HKS cert & a JASMA cert, all it has on the back box is a jasma plate with cert number & silent hi-performance stamped on.
i wanting to swap it for another exhaust to a lad who has a nur spec s & a tsl motorsport middle section as he wants something quieter (he's old) but he thinks it's fake, im after something a bit louder, all the numbers match up but in the world of snide copys you can get anything to make it real.
so what do you all think?
on the HKS cert is say's "muffler" & i had a look on google about jasma & i think it's to do with the DB, street legal in japan is 96DB & jasma must be some sort of testing to make sure it's under that, i think that's what it could be but i could be wrong, but thanks Edd
Hi i have a fujitsubo exhaust on my car but like the other replys the jasma is a stamp for the noise levelof your exhaust.My stamp is on the base of the exhaust also i have the certificate.
Hope this helps
