truck
Newbie
I just posted a thread under the intro section since I'm new here, but what are the most ideal spark plugs and wires for the 350 vortec? (I am assuming there are better spark plugs than OEM) It has 204k with a rebuilt 4l80e
Secondly, the truck has dual exhaust setup with tips, di/do flowmaster and stock cats. Will replacing the muffler with pipes affect anything performance wise? I've read over the years that removing a muffler will affect bp, yet stock cats create enough bp that it wouldn't matter...?
I'm sure there are a ton of threads about this, but if someone could put their two cents in or share a link to a thread, I'd appreciate. Thanks gentlemen!
