Taylor thundervolt 50's

 

ok so ive been researching this topic. Looks like stockers win unless trouble with headers. I have some dyna's and the stock delcos and no issues so I think Ill just go with those again. And for plugs probably just stock delcos again too. Im curious about doing the TR5 but would rather invest in a long term set I think than gain a few horsepower....

 

Taylor T.V, 8.2, Better idle, for me at least.
