Clampable 63-67 Corvette Aluminized "GIVE NO MERCY" Side Exhaust 2.5" Inner Baffle

Fit was very good, the clampable design allows for an easy install. The best part, feels like it added about 70-80HP!!! Absolutely can't believe the performance difference. Previous pipes were Sweet Thunder 2.5" with standard baffle. The sound of both sets were similar, around 93db at idle, the GNM has a deeper tone when dropping the hammer... Well worth it!

Excellent customer service

Still have not heard them since my engine is on back order. They look like great quality pipes laying next to my rolling chassis.
