HP possible from bolt ons on 11 GT
#21
All this is just opinion and a little bit of rank supposition based on the 2005-2009 but this is what I would expect.
Average car on the average Dynojet will make maybe 355-360 rwhp on 87 Octane or 365-370 rwhp on 91 Octane .
CAI/Tune + 93 Octane will be worth around 10% over Stock with 87 Octane.
I used those because I have more data to compare.
Full Long Tubes + ORX + 3" Midpipe + Straight Through Mufflers will be worth around 7.5% more.
That would be roughly 425 rwhp.
Just my opinion. That and a buck will by you a cup of cheap coffee.

It's never cheap nor easy lol. Headers are always a PITA, and with CAI's in the couple of hundred range (or more) nowadays I don't consider them cheap anymore. Cheap was a $30 3 inch air breather, 150$ pair of longtubes, 10$ distributer recurve kit, a 150$ cam and a six pack with your buddies on a weekend. With a header/CAI/Tune/cat-back combos reaching well over $1000, nothings cheap these days.

No kidding. when the GTO's first came out the cheapest header was like 600$ I can now find them for a hair under $300. It's still messed up my brother just bought a set for his 94 silverado for less than $150 .
