Hey guys im looking to do a custom downpipe for my car. Some people tell me to go like the stock desing with 2 inch pipes and others just to go 1 pipe in 2.5. If anyone can help me i would appreciate it.

 

Well it all depends on what you're planning to do with it. If you're planning to turbo your car than the 2.5 in piping would be better, however if you aren't going turbo than 2 or 2.25 would be ideal as this would sacrifice the least amount of torque and free up some upper end hp.

 

No, im not going turbo
