performance ideas that work

99' droptop · 03-11-2000, 10:14 AM

I have a 99' GT convt. that is bone stock. I had some ideas and was wondering if anybody had any feedback on combos that work. I want to get this year the following: Flowmaster Force II cat back, March Ram air system, and pulleys. Any pros and cons on these items or any other ideas on how I can make this thing go any faster would be great.

Go with a set of 3.73 gears, that will really wake up you pony. I wouldn't waste my money on ram air, from what I have heard it sucks(Gets scraped on alot of curbs, gets alot of dirt,birds,leaves,and doesn't work untill about 70 mph) I would go with BBK chrome fenderwell kit.

I just bought pulleys from Steeda. I should have them on in a few weeks. I'll create a post when they're on and let you know what I think. I agree with getting some 3.73s. Instead of a cat-back, consider a x/h pipe with cats. It's more expensive but you'll get more power from it. Do you have an auto or 5 spd? If a 5 spd, you may want to consider getting a better shifter. I had a Steeda Tri-ax on my 95gt,loved it, and plan on getting one for my 99gt. Other mods seem to only provide small hp gains unless you go with NOS or a supercharger.
