Hello all, I am just about ready to pull the trigger on my exhaust. I have been gathers a ton of information on here.

Question one: Is there a difference in sounds between SI/SO & SI/DO? If so what is the difference? Looking for the the deepest tone possible not so much to be annoyingly loud.

Question two: Hear is the cheapest place that I could find the mbrp that I am looking at. I have a 2005 6 1/2 box, supercab. Is the 6 1/2 considered short bed (because I know they make a 8ft but they also make shorter than the 6 1/2)

If you click on the link on the right hand side it tells you to pick the submodel here inlies my question:

Thanks all.

 

Autoanything will beat any advertised price http://www.performancetruckproducts....ts&product=355 And yes that is the short bed for supercab

 

Thanks. Now I am just stuck between SI/SO or SI/DO (45 degrees out the side).

 

I'm going with SI/SO (as soon as my Roush kit sells) just because everyone around here has SI/DO and I like to be different. The MBRP 3 1/2" system is probably the deepest one out there from what I've read.
