Pinnacle Performance http://www.pinnaclepowerexhaust.com/index.php. Their E-Bay Store http://cgi.ebay.com/ebaymotors/Dodge...mZ180211317426
I used to have one on my '98 12 valve, now I have a 5 inch from Full Spectrum Performance http://www.fullspectrumperformance.u...d_fsp-exh.html. Full Spectrum has 4 inch straight pipe exhausts as well.
My 4 inch Pinnacle exhaust lasted 7 years up here in New York. Exhaust fit was awsome and price is nice too.

 

I have the full spectrum 5" into 2 4's
