Hi group, 4 my birthday my wife got me an Edelbrock Mdl#68573, Tubular Exhaust System (TES), for my 1990 Blazer w/350. My question for those of you that have this installed what problems did you run into when you did the install ? The directions seem pretty straight forward and I would like to get an idea as to what I have to look forward too. I hope I can get this installed in a day for my truck is my DD. Thanks Dan..
