hey guys i recently bought a 5in dual stack kit with mitre ends with no mufflers, will i have any problems when the truck isn't running like snow or rain getting to the motor or causing future problems?
No you wont have any problems, however one draw back is you will cover your truck with soot. You can put coffee cans over the stacks but use the plastic can because the metal cans will scratch the chrome.
No worries. The amount of water that gets into the stacks are minimal unless the truck sets for a long time. Once the exhaust gets warmed up the water will turn to steam and find its way out.
