ok thanx alot for your help
hey do you think the inlet and outlet make a difference cuz i notice that they have a staight desing and a of set design

 

My batteries in the cam are dying, so I couldn't get a flash, so I tweeked with the image so the pipes could be seen. I have already cut a good portion off thepassenger tailpipe and still need to grind it down a bit flatter.

Also most tubing you buy that is prebent is designd to use an offset/offset muffler. If you have your own made, then you could use whatever you want, or even if you go with dumps [:@].

I don't know this for sure, but I assume a center/center muffler will be louder as the flow is straight through and has a shorter path than the curve in an offset style one.

Oh yeah, these are the Pro XS muffler. (40351)
