Which bolt-on is the best combo with an exhaust?
Well, I'll be ordering me an exhaust in a few weeks once I get situated with college. Currently, my 94 z28 is stock. The exhaust will be a set of magnaflow's.
So after I get the exhaust, what would be the best second mod to get? Do not count headers. How much more HP should I expect to gain with it?

Cold air intake is a must with exhaust, then go with a cut-out, 3.73's or 4.10 gears (depending on trans), a tune, drag radials and a few suspension bolt-ons like springs, rod and subframes. That should be a good start.

Yea, the cold air intake was going to be my second mod. I'm just having a hard time deciding on what to do with it. Use a K&N one for about $200, get one from eBay for about $80 with a K&N filter, or try to make my own using some sort of induction with a custom fiberglass hood I'm going to work on sometime soon(I hope).
I haven't heard much about suspension bolt-ons. What exactly will I benefit from those? I've never driven a car with them and as far as I know, no one around here has any.

hey N20LT4, about how much better performance wise can you be looking at for a dyno tune? I have LT's with a custom exhaust and CAI, but it hasn't been tuned. Just wondering if it's worth the buck for the bang?

I may actually try this. I've never taken the stock off, but I've heard that there is already a whole there going into the fender with the stock. Is that true? If so, then I do believe that I'll just go get me some pipe and take it to the shop and cut/weld it into place with a k&N filter attached to it. What all will I need for the whole thing? The pipes, K&N filter, and what else? Any clamps? Can I use what the stock one uses to connect the new one to it? How will I know what size of pipes to use? Would it be a good idea to get some high temp engine paint and spray on the pipes to protect the pipes from getting hot and turning the "cold" air intake into a "hot air" intake as much as possible?

Yes there is a hole at bottom of the airbox where your stock filter breathes from. All you will need is 4" tubing, which you can get from Home Depot, and one more clamp besides your stock one - you don't have to cut or weld anything. Lastly, add the K&N cone filter and remove the plastic from underneath the car by removing a series of small screws and you've got yourself a cold air kit. While your at this, another little trick you can do is remove your silencer (the long plastic tube underneath the intake elbow). I have a 1LE now, but when I did the free mod before I used a cap from a deodorant bottle that happen to fit right inside. Anything you can find that will cover the opening and seal tightly will work and give you a few extra hp.
