BTW, I noticed that you had to be done in time for the games. I had to watch my Raiders lose! Who's your team?
Last question...
Do you know if these are street legal in California? I think I remember you saying that the emission laws are tough where you live. I've looked at the DMV site and I can't seam to find it.

I dont know, I would think so since they are cat forward. My issues here are OBD2 if a catalyst inefficiency code pops up.

And I'm a niners fan, getting ready to watch them play Detroit tonight. The niners are looking very good right now. Currently I'm watching RG3 and the Redskins trying to pull a win out of their hat lol.

I just did a bit more research and they have passed all the tests! So now it's decision time. S&B CAI with the scoop, or these headers. Hmmmm!!! The CAI is WAY easier to install, but which will give me more HP???

I did the JBA headers first....in fact I still haven't gotten a CAI lol. I have the headers magnaflow ypipe, magnaflow cat-back, fastman throttle body. She drives like a dream. Fast as all hell. Had a few people that were jaw dropped surprised when they tried to jump on me and I blew past them like it was nothing. When I do get the CAI, I decided on the Vararam though S&B was my second choice.

Headers will give you more of a gain, but all of these bolt on performance parts are helper mods. Everyone you do will compound what you have already done.

Maybe easier and more cost effective than the Magnaflow Y pipe mod? Says its for an 04-05, I dont see whats different on my 2012?

Y pipe won't really add more power as much as it'll just help increase the exhaust flow and ease up some back pressure. The headers add more power than a CAI hands down, the CAI just gives a smoother air flow into the engine along with a better throttle response. Overall HP power gains aren't that much with CAI's in general, it's not until you add in things like headers and a better flowing exhaust system that a CAI is beneficial to your vehicle.

Logic tells me you're correct. All of the parts being discussed must be working together. A better air intake can't do much if the exhaust can't get it out fast enough. And the other way, a better flowing exhaust needs more air coming in to work to its potential. Is that basically the truth?? I'm new to doing all these mods, so I need all the help I can get!!

Basic rule of thumb is More Air In = More Air Out. To move the air coming in at a higher rate you have to improve the exhaust flow. the tips which is the same exact size piping you get with the Magnaflow exhaust kit. The best way to think of this is like sucking/blowing air through a McDonalds straw. If you try blowing air through a regular straw you get a narrow restricted flow, but upgrade to the Milkshake straw and it's much more effective. Every mod supports the other, support the exhaust with an upgraded intake and it will become more effective.

How the hell this motor makes 390HP with those stock manifolds is beyond me though lol However I will say the stock exhaust is about as good as it gets. It's 3 inch piping to the muffler, than splits to 2.5" after the muffler to the tips. I just wish I could get my hands on those 5" exhaust tips, they are so damn pretty lol

I've read a lot on our exhaust system and that's why I'm only doing the muffler, Y-pipe and tips(not functional just look pretty!) Now that the JBA shorties have past the CA CARB tests I'm gonna get those as well. Combine all that with the S&B CAI W/ scoop and I'll be happy as a clam! The only esthetic mod I plan on doing before or just after is the bed liner.
