I'm looking into a 97 f350 7.3 powerstroke turbo and If I get it I just wanna kno are stacks good or bad there is no doubt that they look good I'm just wondering about performance

 

Not sure about the look good part; however, having an after market exhaust alone will not give you a significant increase in HP or torque.

 

Don't do what I saw a guy with a Dodge diesel do -- he had one big 9" pipe in the center for his stack. Probably worked, but looked really ugly.

 

IMO stacks are great... On semi's or larger trucks like that. For a small pickup I think they are stupid and pointless unless you use it for mudding/deep water, so they don't get clogged. Other than that it's silly. However, if done properly on the right style of truck it can look ok, but that rarely ever happens.

 

I'm not shure on the performance but as long as you get them the right hight they look badass
