New member introduction

[Ivantheterrible]

Hello all! I am new member on here and was wanting to introduce myself. I have a 1997 gmc Sierra SLT 5.7L Z71 with 190k miles and all stock! I bought this to use daily as well as on the weekend for camping. I've started by replacig the spark plugs, sp wires, oil change, purchasing new aftermarket headers but I'm stuck on what type of muffler to use.. If you could give some suggestions it would be appreciated! Also I found a leak that I can't seem to trace, it is soaking the driver side wheel well and the oil is black.. Maybe the gear box? Any help would be appreciated!

In response to your oil leak, it may be a oil cooler line leaking. I had a very
bad leak on one of mine, that was also soaking my wheel and under carriage
found out how to repair it here @ the forum. Not saying that is the problem
but worth looking into. Thanks for your post.
