I learned something this week
I installed a test pipe last weekend, I knew it would be louder but never thought it would effect my gas mileage. Since I installed it I've been going though a tank of gas faster than I usually do just for regular daily driving. Any thoughts?

i have a 98 spec (obd2a) in my 2000 itr (obd2b), i have an O2 sensor in the exhaust manifold but my test pipe has a bolt in place of the second O2 sensor so i didnt connect it. will i have the same problem?

No it's OBD I, 95 LS without the sensors. I had 2 holes for the sensors but sealed them. It’s only staying until the weekend, dyno day & track time at MSR. After that the cat goes back on. I can't deal with the added noise & the smell. I'll post photos of the weekend.

Damn, I not throwing any any warning lights but I hoped buy adding this would result in more power.

limp mode is when the ecu cuts off the fuel like @4k rpms. but richening the fuel and retarding the timing is helping to safe gaurd the motor.
