Exhaust problem
So im a US Army soldier that has been stationed in Germany, and i couldnt leave my Trans-Am behind, but Germans hate loud cars. I have an 89 Trans-Am that has all sorts of holes and problems with my exhaust system so i need to replace it being its too loud... I don't want a quite little car, but highest is about 90 decibals to pass inspection, so i need help what size pipes, and how I should build my exhaust so that its around 90 decibals, but not super quite cause i like it loud. It has a bored over 305, any suggestions?

Re: Exhaust problem
The dynomax systems are fairly quiet and cheap

I liked the hooker catback when I had my 89 RS with the 305; very respectable at idle and cruising but nice growl when the foot was in it. Inexpensive, but wasn't stainless, so it can rust out.

Re: Exhaust problem
How much did it run you to export to germany? When I was in japan I wanted to export my camaro to japan, but it was around 15,000$ to ship. But for a car like a skyline from japan to usa ran around 8k$
