[TR] '72 TR6 Exhausts

[Martin Secrest]

Looking to replace the exhaust on my 72 TR6. Currently it has the Monza dual exhaust, which I like, though a long time ago I added internal pipe baffles to quiet it down. It's roadworn now and I want to return the car closer to stock. It still has the stock manifold. 

Is there a "stock" system available that is maybe a little grittier than OEM? I wouldn't mind a little bite.
