Ok guys I have underdrive pulleys, CAI, w/ stock 3.08 gears. I cant decide between catback+x pipe, or a new trickflow intake. My question is will the intake produce more hp on the stock exhaust then if I went stock intake, and new exhaust?
Gears, were my first choice and WOW. huge difference. I recently did the upper and lower intkae and throttle body, the best part of that was I got a wider smoother power
band then I did headers, off road h-pipe and flowmasters. the exhaust help ALOT around 4,500 and up feels like I lost a little torque but it more than makes up for it on the top end, but I would still do gears first.
The intake would probably give you the more HP's compared to the new exhaust, but I have to go with the Majority on this one. Get Gears it's by far the best mod to a stock stang.
I can't comment on going from 3.08's to 3.73's, however going from 2.73's to 3.73's is a wonderful experience. Before the installation of the 3.73's my car was pretty boring even with the full exhaust, and now I can't get enough of driving it. You would think it would get old after a few thousand miles (more like 7k), but it doesn't. It's still fun to drive.
another vote for gears. Then I would do exhaust. And inkake last. The intake will get you the most power but it costs more and there is nothing better than a good sounding stang.
