Not sure what brand this is, do you?

It has a 3" pipe

 

well after many days of searching here is what I found at

www.modacar.com





The HKS Turbo Exhaust Cat Back Systems are specifically designed to work with Turbocharged vehicles. Each Sport Exhaust System is constructed using a chambered, aluminized steel muffler assembly and piping, high-quality computerized welds, and polished stainless steel tips.

Photo may differ from actual product depending on tip.

 

Looks like one of the old M2 Dual Exhausts.

 

Thanks. I replaced this catback and now it is on ebay for 200
