What type of exhaust do you have?Ok so that’s the sound I been hearing once I hit over 4 thousand rpm lol
I remember the red cherry bomb mufflers. All they did was add 25lbs to your ride and magnify the cis….That stupid, 75 Chevy truck with straight pipes sound. Pop pop pop pop pop pop when they're gassing on it, and they think it sounds good. Instead of CIS, it should be SLS. Sounds like ****.
