So after four years with my ROR kit, I'm fed up with it's crap quality and lethargic sound. I know some folks will hate me for saying this but... but I have always been a flowmaster guy and after hearing my brother's truck with a sido super 10 im sold. It's slightly more aggressive than my ROR and a bit louder and I think it is exactly what I've been needing on my truck. My question is that I've heard that there can be a different sound between 45ing it or sotb even if the engine and exhaust are all the same otherwise. What do you guys think?

 

They definitely sound different, personally I prefer the sound of 45'd tips verus sotb. Without taking drone into consideration, the sound you hear is once the exhaust exits the tip so single out the back the sound is coming out the back of the truck, whereas with 45'd tips the sound is coming more from the sides, on both sides. With 45'd tips the exhaust will echo off of anything beside you as well but with sotb there's really nothing for it to echo off of.

 

If you tow a trailer, get 45's behind the rear wheels - SOTB and trailers gets ugly.

 

Ok so I doubt one way would actually be louder than the other, but 45'd should maybe project the sound more fully? Do ya'll think it would still be as loud to the guy behind me (so to speak) as sotb would be?

 

45'd will be louder to you because the sound is being projected closer unless theres someone tailgaiting you to project the sound back to you. Sotb will be louder to the person behind you since the sound is being projected torwards them.

If you want to get a quick idea, start your truck and stand behind it. Then move around the side of the bed where a 45 would exit, you'll notice a slight drop in how loud it is because the exhaust is being projected in a different direction, the same concept applies just on a larger scale.

 

Ha ha, don't know why I never thought of such a simple test. Yes it is a touch quieter from around the side but not much. Ok so really not a huge difference sound wise one way or the other. I do prefer the looks of 45'd but I have to decide if I want even more of a headache keeping the tips polished than I do now. Thanks for the replies guys.

 

Couldn't have said it any better myself.
