I was wondering what your take was on a couple of things...
When i had my '99 GT, i had a bunch of bolt ons but one that gave me the most "seat of the pants" performance was the underdrive pulleys. Also the first thing i did to the car was replace the stock mufflers with Mac Flowpaths. Later on i ended out swap'n the whole thing out and going with 2.5" catback form SLP. What a mistake that was. It was as if i LOST power, mainly at the bottom end. Its like the thing wouldnt even get off the line to save my life.
So, do you think that i would have the same effect with the pulleys on a 289 like i did with the 281pi or would it be a waste of money?
Also, does anyone know why i would looses power when going to a catback system? And should i leave my stock 2" exhaust the way it is (stock pipes with Autozone type turbo mufflers) or go bigger and whats the biggest i should go?
