Hey guys, this is my first post but have been watching it for a few weeks now. And first wanted to say that this is a very nice community. I just picked up a silver 05 and was wondering if a Maggie would be my best bet or could I get the same amount of power naturally with heads, cam, intake, headers, exhaust, etc. for less money. The parts add up to be about the same in price but I believe there would be a lot more labor with the Maggie. Correct me if I'm wrong. Thanks in advance guys.

I think it would be the other way around: Maggie is primarily a bolt on, but with heads and cam you have to get into the car a bit more - Maggie folks are going to say get a maggie and heads and cam guys are going to say heads and cam, but then there will be folks that have both. Once you hit either mod hell you are doomed

MAGGIE all the way

Yea i think maggie by herself gives the best bang for the buck. It's more of a complete package. Just swap out the intake manifold with the maggie and your set, new injectors and all. It took me about 12hours to install mine back in the day. I did sell it and end up with cam and headers though. I had some trouble as my maggie was used. Just get a new maggie and i think you'll be fine! I do like the sound the cam sound more than the maggie though...

Yes to what they said ^^^^. Though I don't have either, a maggie will keep your car more of a sleeper while H/C will make your power more obvious to others. I still am trying to decide which route I'm going too. The headers & exhaust should be done regardless, and a maggie installed should run a bit over $7k. I feel like you can get H/C/I installed for a bit less than that.

Would I be able to make as much power the naturally aspirated route or does the Maggie make more power? And what Maggie are most of you guys running, the M112 or the M122. Lingenfelter said if I went with the M112 I wouldn't benefit from heads, cam, headers, or throtte body. He only recommended exhaust. Thanks again.

You'd want the 112 - you'll have to build your motor to handle the 122. I don't think anyone has run the 122 in these cars yet.

qqik4u, rand49er are both making about 480 rwhp with M112 w/2.8 pulley and full exhaust. You can get more boost with a 2.6 pulley.

I don't recall anyone here with that kind of N/A power.

Someone else is going to have to chime in.

Didn't know the 122 was out for our cars already. Isn't the 122 too much for a stock LS6 internals?
This is why I'm going with a Maggie. I like to install the mods myself, and the Maggie just bolts on. I'm not going into a motor. The Maggie is instant, everyday power and very usable.
N/A, you have to know what everything does, how they will work together and how all that will affect the way your car drives. I would have to turn my car over to a shop, and let them decide what I need.
Trukk just spent $4000 on a cam. He went overboard, but the parts do add up.
I think going N/A will be much more $$$ for the same power.

Let us know what you end up doing. And post some more info on the LPE 122. Your not the only one looking.

Hard to find a H/C package that will give you +100hp.

No reason to tear a running motor apart unless you want to.

Maggie is less install hassle then H/C.

I like mine so much I bought two!

OK, you guys talked me into a Maggie, but do you agree that headers aren't benificial with a supercharger?? Or do I just go with the maggie and a cat back?? Thanks for all the helpful info!!

OK - Not speaking in technical terms - I had my maggie and my B&B exhaust done at the same time as I bought my car all new (+car) in o6. So that is the way I think CTS-V should have been always. After six months I added the headers (kooks), but then replaced the B&B only reason was that I did not want any fab work on my car so Kooks are a perfect match with corsa not with B&B.

After adding the headers I noticed the major difference in sound and I loved it. But also the car felt stronger in the pull on the straights. So real experience I like the headers - so start slow then add as you go.

Most people with maggies end up changing the exhaust system.

The better it breathes, the more power you make.

Isn't there some benefit to back pressure on a forced induction? Mine always "felt" faster when i ran the maggie with my cutouts closed. Some on the forums said it prob was due to the higher back pressure... I have no data to show it actually was faster. Maybe just hauling ass and still being quiet was unexpected, so it could have been all in my head.

Heads/cam is usually less, unless you bought StealthV's Maggie...

If you have a free flowing exhaust you will generally lose a little torque down low but pick up some HP up high. You usually notice the loss of torque because thats where you drive most of the time.

Hey,

If i were to do it over again I would go all motor. Summit racing right now has package from trickflow. it is 515hp kit comes with matched cam, heads, rockers and all gaskets. this is complete kit and it was arouund $3100 for package, which i think it is good deal. You would just get package for LS1 motor. 515hp was rated with LS6 intake so it is perfect for 2005 LS6 motors. This is all tested with trickflow so don't waste time putting kit together. with this kit car would make 450rwhp which is very close to maggie power number. best kit for sure.
