I tell you what, I only have 95k miles on my 2004 Mitsubishi Lancer ES 2.0L The Check Engine light drove me bananas for 2 years, I changed the exhaust manifold, the O2 sensors like 3 times to all sorts of quality ones. Nothing worked! But then, I found this Catalytic and I said, Why not just give it a shot? I bought it, I got it in. Check Engine light is gone! Drove already 1000 miles on it, now at 96k on the car, no light and the car feels like new again! Thank you for saving my car!
Threw these in a 96 f250 with the 5.8w unlocked power and performance. It runs like a dream on the highway and is my daily once again. OBS fords have a huge bottle neck with intakes and exhaust so these headers will change everything. They bolted right on no machining needed and everything came perfect in box with all the hardware. They are deff pricey but will blow away any cheap header that%X92s not coated or just not as high quality in the long run.
