Sounds great and decent install

Summit RacingSummit Racing Verified Purchase

89 Firebird Formula 350. I wanted to use all the stock locations and tailpipes. I also wanted to avoid drone and obnoxious exhaust cracking. Once I found the right angle this goes in and the right tips, it fit fine and the sound is exactly what I wanted. For the exhaust tips use Walker 43243 and 43244 not what is listed under applications.
