i am wondering if a catless y pipe will make a difference in my truck, and also about how much they cost?? and if i would need to get o2 simulators aswell
thanks

 

can anyone help me????????????????

 

When I make catless y-pipes I usually just weld a couple extra bungs in and put the sensors back in. A few bucks for the bungs is cheaper than the sims. I don't think anyone is making these yet, though, so you would probably need a custom job.
