use a bolt on, simplest way to go. Tips don't matter at all..so if you feel the need to buy a name brand....it will be no different from an eBay special

 

I say bolt on, always... no need to limit yourself in the future. Like lowmpg said, they're all the same. I say go cheap. I personally think +1" over your exhaust size is the way to go. I'll post a pic of mine here in a bit but, again, it's nothing super special.

 

Yeah I was thinking 4" to 5". What length do you think? 12" or 15"? I haven't had much luck looking for specific images

 

Unless I'm mistaken mine was 16" or so. I would go longer; you can always slide it further up the tail pipe to get your desired look. Here's a couple crappy pictures.

 

I have a 5-6" double wall exhaust tip and think it looks great. It's 12" long, but OH was right about longer tips being slid further up the pipe.

 

Here's another crappy pic....

 

I'm with these guys, just go with an ebay/amazon bolt-on. And if your truck is stock height/tires a 6" would look perfect. If it's lifted or has 35's or bigger, maybe an 8". My 6" tip looked massive when I got it, then I put it on the truck and it looks like a stock tailpipe on a gas truck Also, definitely get a 16" or longer, I hate how short my 12" looks on these big a$$ trucks!!

 

6 inch for me. I think it looks good.

 

I was in the same dilemma.. I had bought a Flo-Pro tip at the same time I put the exhaust on the truck. Couldn't make up my mind about the tip because the stainless looked fine to me and I didn't want to cut a chunk off to put the tip on. Anyways, this past weekend I ended up cutting a bit off and put the tip on. Mine is 7" and 15" long and looks great. It is black so I'm not sure how the coating will hold up with the tire throwing rocks at it. I'll have to get a picture
