Which headers should I get
I have Solo High Flo cats, but they will probably go bye bye. I also have the SLP PowerFlo X-Pipe and Loud Mouth II exhaust. I was thinking of just getting SLP headers that bolt right on to their X-Pipe.
http://www.slponline.com/view_product_site.asp?P=30212 Any thoughts? Would there be a better option that fits my current setup? I had SLP headers and exhaust on the '02 Z28 I had and the torque curve was pretty good. Only bad part was the ground clearance. Although I haven't really noticed anyone complain about ground clearance with SLP headers on the LS3. |

Honestly man if your into spending $1000 to gain 8-10hp...I say go for it. From the info I have gathered, the biggest difference to be had is in the high flow cats which you already have. I'd spend my money elsewhere. The factory manifolds flow pretty well. I'm not sure what you have done to your car but here's some better ideas for your money:
-cam -tune -under drive pulley -gears -cnc ported throttle body -tune -buy lighter parts I think you could do a tune, tb, and pulley for less money but get more gain. Just some things to think about.

All of the above plus I will be installing a Cold Air Inductions cold air intake once I receive it. I was planning on getting a tune, but I would hate to get a tune, mod some more and then spend another $500 on a tune. I guess I could always just get it dyno'd after the CAI is installed and decide after that what to buy.
Do you really get anything from adding a TB? I did that on my LS1 and didn't see any gains. Doesn't the underdrive pulley usually affect the AC or power output? What kind of labor is involved with installing a cam, and do you need to replace the springs, retainers, and locks? This is what I used to have. 2002 Black Z28 M6 375 rear wheel horsepower SLP parts-CAI, 85mm MAF, bellows, cam, springs, retainers and locks, double roller timing chain, headers, y-pipe, high flow cats, Loudmouth II Unfortunately I stopped keeping up with the LS motors after the LS1. So I don't know the best mods anymore. The Z28 I had ran 12 flat in the 1/4 on street tires. I would love to do that or better in my new SS, but right now I don't wait to spend too much money. A tune costs $500. So let's so I have $1,500 to play with, but it MUST include labor. As in, I am not doing engine work myself. Easy bolt on stuff, I will do, but that is about it. So from what I already have, what is the best $1,500 I can spend? |

Why is the tune $500? Mine was $200. The tb helps a little bit. About 5-8hp, the pulley about the same. Guys on herehave said it doesn't affect the a/c or anything really. That's my next mod. Do yourself favor, get a Vararam. It really works. I could not believe the difference mine made...it was noticeable big time. Maybe buy some drag radials? They will definitely help.

Good news* You won't need a tune with that cai, and you'll see roughly a 13hp increase at the tire. Porting the TB will give you an increase in throttle response, but no hp gains. Not so good news* Under drive pulley has negative affects on your power supply in your car and to me isn't worth the scratch. 1500 bones won't get you much, my choice would be headers to compliment that cai, get the TB ported and get a tune. You should be good with the tune with other bolt on's until you go cam/forced induction route. Cam- retainers, springs, pushrods will all be replaced/upgraded, labor takes the better part of a day. 3 bolt cam is a good choice. Spec's of course are up to you. Ask around the site there are plenty o' good folk here to help with your build. |

Here is a link to an article on our blog about selecting the right header for your application.
Choosing The Right Headers It explains some of the technical aspects as well as what makes a quality header. If you have any questions feel free to send me a PM. |

Based on what I am reading, it seems like the Kooks Stepped headers would be the best choice. My only concern is how it will connect to the rest of my system. They sell catback connection pipes, but it says for 2.5" exhausts.
I have this. Solo High Flow Cats SLP PowerFlow X-Pipe - http://www.slponline.com/view_product_site.asp?P=30220 SLP Loud Mouth II Axel Back I am guessing the Solo High Flow Cats will end up being removed, right? But the SLP X-Pipe I have is 3". So, what do I use to connect to that? |
