Finished my exhaust today. I installed Dynomax Headers and a 2 1/2 inch true dual exhaust w/flowmasters (series 40) on my 79 GMC 4x4.
Big difference in throttle response, huge difference in acceleration, added top end. Im very pleased with the performance. for 456$ total, thats a good deal! In high gear i can put the pedal down and it takes off. The pedal is so much 'lighter'
However, do flowmaster mufflers take time to louden/break in? I was expecting a loud rumble but its quite mellow, still good though! Im happy with it anyhow! Anyone interested in some pics?
