Just got my '06 Goat Q'silver/red M6 18's. My first new car!!! Yipeeeee!
Now I'm looking at upgrades to intake and exhaust. I am looking to see if the K&N intake is a good choice for the car. I heard a rumor that it might rob torque, but that may be a crock. Please respond with your feelings on the issue, my fellow members!
I would go with a Volant if you decide on the intake. I personally have a k&n and I am thinking about selling it and going with the volant, and as for the shifter I believe it allows more accurate control over the shifter but I have an a4 so that is purely speculative.
If you change your intake,, buy the A.E.M Brute Force system..K&N, Lingenfelter, Violant and others are good and all of them will give you about the HP increase but the AEM systems uses mostly light weight aluminum instead ,, the others use black plastic, this black plastic will run hotter and hold the heat much longer, the aluminum keeps the air cooler and the cooler the air going into your engine, the better it will run,, trust me on this one, I just retired as a engineer with Pratt & Whitney Aircraft and we did all kinds of testing on jet intake systems, tried all types of materials, ,, looking at ways to increase air intake and cooling the air intake
yes,, there are ton's of parts showing up for these cars and it is hard to make a choice what to do, but for your 1st mod , an intake system is a good start, all of them cost about the same which is about $260.00 ,, not hard to install but you should get a Dyno tune to get the most out of it, but you DO NOT Have to do one..also for about $50.00 you can get a Vararam throttle body spacer [ on ebay ] it will give you another 4 or 5 HP,,only a few minutes to install, and if you are going to put in a Cold Air Intake, you just remove your stock system and while it is off just remove the 4 10 M/M bolts that hold the throttle body, put in the spacer and then put everything back together, I did mine and it took about 45 minutes to do everything.
as far as exhaust, again there are a lot of good systems, I did a magnaflow cat back as my 1st exhaust mod,, great sound, more HP and cool looking 4 inch tail pipes. this system is around $750.00. plus labor, which should be around 200.00 dollars
what you'll find in these types of posts are opinions as to color, sound, "feelings", reputation, my favorite one "dyno results" (which doesn't directly relate to street performance), seat of the pants dynos and on and on. what you won't find are concrete measurements of MAP @ WOT over RPM ranges (most do OK here as it's related to filter size) and air intake temperatures at stopped, heat soaked conditions and the transition time to a cooler intake temp. all that that i have actually measured don't come out as good as they'd like you to believe.

PS a good shifter like a GMM or a Billet IS the best first mod. if you can't shift fast you can't go plus it's something you'll use every day and enjoy. my little bone stock with stock tires '04 except for a GMM shifter got a 13.3 which easily beat most of the LS2s with aftermarket "hot" air intakes
