When cleaning the car recently, I made out the logo on the huge Exhaust tip - JAZMA. I looked through my service history and came across the diagram for my exhaust - cat back.

The piping is huge, i'm guessing 3". Are JAZMA good? I've never heard of them?

JASMA isn't a make its the japanese standard of exhausts

The exhaust isn't the standard one though, it's a 5" slash cut back box, and the piping is bigger than standard, or am I being thick

Sorry didn't mean standard as in OE i meant it as meeting standards of manufacturing.

Nick_Scooby

So would it be as good as any other performance exhaust manufacturer?

Its very broomy!

JASMA don't actually make the exhausts just make sure they comply with japanese law (so Blitz,HKS etc have JASMA approval)

Not the best translation but you get the jist

Nick_Scooby

Thanks for that! Got the jist of it....I think

So the make of my exhaust could be something I'll never know?

Yep but if you're happy with it don't worry

Nick_Scooby

May sound thick, but whats the easiest way to find out the thickness of the piping?

I suppose the easiest way is to remove the backbox and that should leave you with easy view of the centre secion (i'm guessing by the way)

Measure the circumference of the exhaust with a measureing tape and divide it by 3.14

Thanks for that mathematical approach!
