I will be dropping in a .18 TZ in my MT in the next couple of months. I all ready have the engine but doing some research on what tuned pipe I am going to run. If you want food for thought check out this article as it says from the factory .18 TZ put out all most 2.3 HP. More HP then some big blocks.

This is the pipe I think I am going to run but that is not final right now.
