Have to chg mufflers lets hear your thoughts
I changed my big block out of my 70rs to a stock ls1. Stock for now I will cam it and change intake as soon as I finish and make sure everything is right. It sounds a little mild, no its not good at all. It has 2.5" duels with an H pipe and the exhaust dump just behind the rear tires after going over the axle. I don't want it to scream at me but I need a little muscle sound about a 7.5 on a scale of 10 I thinking Magnaflow and even at that I don't know which one is the best. Thanks for any help or comments John
