Yes,I noticed a big difference. I have a 99 gt convertible 5 speed stick.I had done every bolt on you could do, so the next thing to do was the cams. I had the stage 2 Crower Cams done at Alternative Auto in Chesterfield Michigan. I gained 29 h/p at the wheels. The car put down 295 RWHP and 305 foot pounds of torque. The car is faster than the numbers suggest. Much more fun to drive and I get compliments on the rumpy idle. The exhaust is full length headers in o/r x-pipe through three chamber Flowmaster's. It's not cheap though. Cost me $1,900 cams and labor with custom tune on the dyno. Look up alternativeauto.com for more info. He's always worked on my mustangs and love their work. Very knowledgeable. You can call and get his advice for your car. Hope this helps! One last thing, before I had to shift at 4500 rpm, but now she pulls hard all the way to 6200 rpm. If I lost a little low end torque it's barely noticeable with the tune and the sound and feel of the car was worth it for me!
