Fabspeed vs GHL Exhaust
#16
Are any of you getting any resonance/vibration around the 1700-2200 RPM range? I know the AH probably won't get it based on the design, but how about the other systems? I have Dansk Pressed Sport Mufflers and tips which are based on the OE cans, but i get some low end resonance under load for about 10-15 mins until they warm up. Great sound@ WOT, but the cold resonance is a little annoying.
