I cant get to crazy yet, the wifey was really nice in letting me get a 2006 GTO (LS2/A4 combo)as long as I sell my 2005 ZX10r.

Air intake kits - What works, what is the best bang for the proverbial buck?

Exhaust system - Dont plan on doing headers yet, but for a catback or muffler setup what can you all recommend. I was thinking of just replacing the stock mufflers with Maganflow mufflers.

ECM - Is it going to be worth it to reflash the ECM before doing headers?

What are some of the minor bolt on 05/06 GTO's doing?

Functionally, they're all pretty much the exact same. They all pull air from basically the same location, they all seem to use the same K&N drop in/cone filers.

Depending on who you ask.. you'll get varied answers. Some will claim they can feel the power increase, some will claim better dyno numbers. Others will claim that once the heat soak sets in, any power gains will be moot, because while the intake will be sucking in more air... it will be hot air.

Something to think about.

That would work if you want to save $$$. I personally like Magnaflow. The stock exhaust does have some restriction points to it that you may want to give attention to. If you don't want to fork out the $$$ for a complete cat-back, you could always buy the mufflers you want and have a local exhaust shop fab up a nice setup for you.

I would wait until after headers before reprogramming the ECM. Stock tuning can handle an exhaust/intake combo without too much fuss. But if you get headers, then yeah... go get a tune.

These cars are pretty rich from the factory to begin with, plus with a tune you can get rid of stuff like Active Torque Management, etc. But I personally would wait to do this until after you get the headers done.

You covered most of them: Induction, headers, exhaust. There is also the underdrive pulley which can net you some more power. Since you have an auto, you might want to research torque converters as well.

You could also look into electric cut-outs for the exhaust.

I never thought i would be saying this but get a predator or superchips programmer. I have personally seen these shave 3 tenths off of the 1/4 mile and add about 2-3 mph. The torque management in these cars pulls out so much power, and these programmers delete it (not to mention give you a more mean and lean tune). Normally i would say get a "real" tune but the results these give with minimal bolt-ons is great. Good luck.

I had a Predator with my Formula and loved it so that may be a idea. Hmm, I wonder if they will miss it when I get my stuff out of the car?

I would say get a K&N drop in filter, a stall, and a dyno tune. If you want sound, Spintechs exhaust system sounds pretty good.

Good idea, but the computers are different

Sneakyws6

I was going to sell it to offset the LS2 predator actually...

Ah... Gotcha!

Sneakyws6

No biggie, I wasnt really clear on that...

Well the mods have started. (2) Magnaflow 9x11 mufflers are on their way to me. Now I have to find the CAI I want.

Who has the best price on a CAI for the LS2 GTO? I am looking for either the LPE or the Volant.

Then it is 160 thermo, Underdrive pulley, Headers (Who makes the best bang for the buck ones here) and a tune if I dont go with the Predator.

Trade you a bad *** turbo setup for the bike.....

Sneakyws6

Wish I could but I need to pay the bike off and take the profit to pay off some other things.

Pacesetter cost half as much as the rest of the brands out there. Downfall to them is they're not stainless steel, like the more expensive brands.

But if that's not an issue for you, then there's your answer.

AND have more fitiment problems and customer complaints than ALL others combined. they just "redeisgned" them and still dont fit right

Wait on the 160 until you go get a tune. My CEL was on all winter due to low coolant temp or some BS code. I got it tuned, and have had no issues.

dont forget about drag bags with some drag radials. keep that 60foot donw

And new stubs and axles! They like to break on DRs. So far I have been lucky, but I soft launch to 1.9 60's.

gutted stock airbox w/ K&N until you are looking for the last tiny bit of HP then want the extra hp or two a open element cone & a box will net you.

Believe me, I have cam/headers/tune/nocats/flowmaster/plugs/wires/t-stat, etc. and i was on the stock airbox. Gutted though. I finally hit the point where nothing was really left so I changed to a CAI. No real gain at all, but I got it cheap, and this way I know I did EVERYTHING, until I do gears & heads.

sprayjunkie

Do it!
The stock M6 cars gain a 18-22 rwhp in the LS2 applications!
If you need another tune in the future, you know I'll help you out.
