1999 GMC Sonoma Highrider ZR2 Ext. Cab Shortbox 4x4
I am very satisfied with my Gibson exhaust system. It came with detailed instructions and installed fairly easily in about one hour. The exhaust sounds deep and throaty without being overly loud. I also noticed a little extra power in the two thousand to three thousand rpm range. Ryan
BUY MAGNAFLOW-YOU WON'T BE DISAPPOINTED
The old converter was loose inside and making a terrible sound. Magnaflow advertised that it was a direct replacement; no modifications. WELL IT IS! EXACT FIT! I ALSO INSTALLED A GIBSON EXHAUST: CAT BACK. I noticed that my engine runs slightly cooler, and at acceleration I can feel a difference(not neck snapping but it seems to run better). I was impressed with the quality and the workmanship, it is excellent. Time will really tell, but by the appearance of the converter it looks like it will out last the truck. A couple years back I had the converter replaced at a muffler shop and it hasn't lasted that long: the price was well over $150. LISTEN, IF YOU NEED A CAT BY ALL MEANS BUY THIS ONE, HONESTLY!
super 44 series
I drive a 93 GMC sonoma with a small 2.8 six cilinder engine in it. A tiny engine indeed but equiped with 44's i promis you its louder than the average V8. WHen i hop on the feeway i dont step on the gass as much as i use to in order to reach 65 /70 mph so a slight increas in power wass also noticed. THe only down side of this muffler is that you wont be able to sneek your girlfriend out of her house late at night anymore. Evey single car alarm goes off in small neighborhoods. In conclusion, loud interior and loud outside.
