Hey,
right now i got straight pipes on my truck. still got the cats. here soon maybe in a month im going to be running long tubes no cat and spintech, but i need one right now just to throw on my truck.. there are so many to choose from though! im not really concerned whether its a single or dual out, unless i gain a small fraction of anything either way, whatever you guys recommend.

these are the ones ive been looking at.. help me decide?

Mufflers - Street Mufflers - 5000 SUV/SPORT TRUCK SERIES - 5436..3" center inlet 2-1/2" dual outlet - SpinTech Performance Mufflers

super pro street 9444

these are the ones i have been thinking of, but im not an exhaust knowledgeable guy... so a little help please?

 

Si/so will be cheapest. But we need more info...what sound do you prefer? I can give you a list of spintech from quietest to loudest.

 

i want one of the loudest, but enough so that i will have some back pressure instead of these damn straight pipes.

 

 

pic wont work so I will link it
