I just installed my own designed stacks and it sounds awesome. It is actually queiter on the highway I don't hear the valves as much. The wife even said it is quieter. I fabricated almost everything and it come out really good.

 

oh and to db good to have you here

 

The stacks are QUIETER on the highway than a straightpipe???

 

The engine is quieter I can't hear the valves rattleing. I had removed the muffler and had a 4" tailpipe then I put stacks on then it was to quiet so i removed the cat. Around 2000 rpm's ther is a droning but another than that it isn't as loud as I thought it would be I will get some pics on here.

 

So as far as exhaust noise goes how loud is it compared to a straight pipe?

 

my stacks are a sh*t ton louder then my 5in exbandit.... it sounds sooooooo much better too.... my buddies say they can here my truck comin for about a mile....

 

i got dual 6inch aussies on my 01 u dont hear the valves over the exhaust and dual straight pipes sounds so much better than single to me

 

So the stack are also louder in teh cab than a straight pipe?

 

Engine noise is quieter exhaust is noticeable louder but with the windows up you can have a conversation no problem. Pic's coming saturday

 

Here's some pics I hope it works my computer skills aren't very good.
