2 New Xcellerator turbo universal mufflers, 18" overall length, 14" body, 8"wide, 4" tall, 2 1/4" in/outlets, aluminized components for longer life, easy bolt on do it yourself installation. Made in USA. I did a lot of research and found these to be perfect for sound (not too loud) and quality, -hard to find decent mufflers for our cars that fit. Ended up going with a complete different system and wont be needed these. $120 for both, plus ship. These fit 67-69 Firebirds.
