I am looking for the drawing of the inside of the muffler of a 98 A4 1.8TQM.

Anyone who has access to the software used at the dealer or anything else ?

I need it to build a case agaisnt I ticket I got here in canada, here we don't have laws against Decibel, The law was written in 1986 and basically any exhaust that don't have the same caracteristic as your OEM muffler is illegal! Bullshit nways

For the curious ones, here is the one for the Borla exhaust. (same year)

 

Anyone that can guide me to someone or a site where I could find such info ?

 

I have no idea on your drawing put I would contact your local Audi dealer and see if they could help you out at all
