Exclamation true duals to catback

I switched to a Hooker catback with 3" Mufflex Y-pipe, from a True dual set-up with 2.5" pipes, X-pipe, and 10 series flowmasters, and wow what a power increase, It must have been the flowmasters holding it back, I am going to the dragstrip tomorrow, to see If I see any change in MPH or ET, but the car sure feels better.

Probably just cooler air. Or purely psychological. The flowmaster 10 series flow pretty well.

Its a lot quieter, I love it, it makes it real stealthy now, hides the cam better.

huh? I don't know about that, show me some statistics and I'll believe you. Some times it is just in your mind! I don't think anyone can notice a 5-10 horsepower difference!!! Now you are suggesting that back pressure bullshit, I don't think I believe that ****. Free flowing engine has always produced great numbers.

Well, weather or not it added any power or not, I won't know until i run the car, but it definitly moved the power around in the powerband(with that backpressure bullshit, weather you believe that **** or not). It definitely made the car a lot more fun to drive.
