I recently picked up a 100% stock '94 Cobra. I got this car with the intent of making it a "nice day" driver/autocross car. I took it out last weekend and was VERY disappointed in its performance. The car would not pull above ~4000rpms and I couldn't figure out why at that time. It didn't break up or anything, it would just stop pulling, as it if it was either sucking through a straw or the exhaust was plugged. I yanked the air silencer, bumped the timing to 14* and took it back out for a ride. The problem was still there. I got to thinking that with the miles and the fact that it still had the stock 4 cat H pipe on it that the cats may have been plugged so I decided to yank the H pipe to see what, if anything was wrong and here's what I found.
Driver's side pre-cat, looks normal:
Passenger side pre-cat, ummm, this is NOT normal:
Well, I hope this was the problem, but I'm not taking any chances and I'm putting on my FMS shorty headers too (on the left in the pic). I wonder is they'll flow more than the stockers on the right in the pic?
I'm not sure if I'm going to run a MAC catted H pipe, or my offroad Bassani X pipe as I have both. I don't want this car to be loud and I think the catted H is the way to go to keep it quiet. I also picked up a set of Anniversary Cobra wheels wrapped in 275 series Kuhmo V710 race tires from my buddy Steve. Here's a pic during the tear down... excuse the mess!
Here's a few pics I took of it while I had it out the other day too after I spent hours claying, glazing, polishing, and waxing it.
