Horsepower Gain ???

My car is completely stock right now. I'm trying to figure out what horsepower gains I'm going to be looking at for the parts I have ready to install in the next few weeks.
I have ready to install:
- Magnaflow quadtip catback
- Fast Toys Ram Air Kit
- Fast Toys 85mm Air Lid
- MSD Ignition Wires
- NGK Tr55 Spark Plugs

I'm going to get a set of long tube headers in the near future and an ORY. I'm planning on leaving my stock y pipe for now but might possibly purchase the stock replacement stainless steel y pipe that SLP offer.

Would I need a tune after these mods or should I wait until I do the headers?

Thanks!

And no tuning need just yet. You could, but it wouldn't really be worth the price. After some headers, yeah, it would help, but still not necessary.

the first round of mods you listed....figure about 15-20hp.

the maf could actually hurt your performance, it depends on the car and the a/f ratio that it has with the mods. some guys lose power with a maf, some gain.

putting longtubes on the car will pick up another solid 12-15hp.

don't waste the money on the replacement ypipe for the stock manifolds....not worth the time, money or hassle (clearance). the stock ypipe isn't the major restriction...its the manifolds

Well if the manifolds are the major restriction, maybe I'll leave the y-pipe alone and replace it when I do headers. With regard to the sound of the car..........when I do headers, will the car be much louder if I go with an ORY versus a catted Y. I don't want the car to sound too loud. Will it make much difference?
Any recommendations for a set of long tube SS headers with a matching ORY or a catted Y at a good price that would go good with a Magnaflow catback?
