copb8 82 Report post Posted April 5 Sounds great. Do you have any resonance in any of the RPM ranges? My Flowmasters sounded the same but the drone at 35-45 mph was so annoying that it was hard to talk. I ended up having resonators installed but now the sound is muted and I miss the my old rumble.

rays69mach1 9 Report post Posted April 7 Yes there s some resonance at around 35-40mph but I'm willing to live with that because the rest of the time it sounds awesome. Ray Quote Share this post Link to post Share on other sites
EastYorkStang 25 Report post Posted Saturday at 02:57 AM Sounds great. Makes me want to get mine out of the garage. Just have to put the seats and interior back in my ‘65 El Camino. Quote Share this post Link to post Share on other sites
