Whow I'm impressed! Recently I purchased a GHL exhaust system from another forum member here (Ogopogo). I was fortunate to meet him and his wife at Salmon Arm, BC. The GHL's were exactly as he said basically brand new, thank you so much Larry. Anyway I bolted them on tonight the fit was perfect. OK time to fire them up.........whow what a deep mellow sound. So I let the car warm up and now its time to hit the street........these things have such a low rumble when taking it easy...........look out when you put your foot into it a bit.........these GHL's have transformed my car from a pussy cat to a roaring lion!! I love it. So I take it out on the hiway and run it up to 110-140klm and absolutely no drone whatsoever at these speeds sounds the same as my stock exhaust until you drop a gear and punch it. Ok so there is some pop and gurgle but far less than what I was expecting as I'm not running an H or X pipe. I actually don't at all mind it as its very subtle. Will run it this way for a while before deciding to add anything more. Performance wise, I'm sure the front wheels are now getting air!! LOL (ya I'm pumped) Actually it feels to me there is a slight increase in performance.....it is coming on quicker. Anyway I did a fair bit of research on the GHL's and I'm sure glad I went with them.
