You should of sold the TOG and ordered the full CTI setup, Willy's header is the sh*t! (comes with dp + hi flow cat, too) I went with Corsa Sport for the cat-back, though, hadn't heard any sound clips with Magnaflow that I liked, I'm sure it sounds better in person just didn't want to chance it.

well i bought the TOG header from VictoryRedSS for $160. couldnt pass that up. that CTI header and downpipe is a little pricey for me.

$440 (your setup, I'm guessing at price) vs $700 (CTI)

I see your point...

so whats the guess on the gains here. TOG header, Downpipe w/ cat, 3' CTI Exhaust. Im guessing about 25 whp

From the stock exhaust to the CTI header and dp, plus Corsa 2.5" catback I only gained 12 hp, don't know how much of a difference being 3" all the way back is.

wow i would expect more than that

what other mods do you have??

I see you have hp tuner software listed in your sig, tuning after the exhaust got me an additional 14 hp for a total of 26 hp with my mods. But alot of that gain from tuning was due to the crappy stage 2 tune I started out with, it was running extremely rich.

stage 2 w/2.8"
Injen CAI
CTI header and dp (w/cat), Corsa Sport

and the rest being non-hp mods like poly mounts, cab's, and strut bar

true, its all about tuning, just like the gm stage 2, intenses tunes are a base tune, all the cars that have the stage 3 or 4 tune all have the same tune, no matter if they live in colorado or florida, those are 2 totally different areas, once you car is tuned specifically for YOUR car then you will see some good gains. Also mods that deal with flow will benefit greater from each other the more you have, such as I/H/E you will see a good increase but drop a pulley size or 2 and you will see even more substantial gains, because of running more boost but with the upgraded I/H/E air will flow alot more freely.

but that will cost some crazy money to get it custom tuned right. i mean i got screwed ont he Bin File and Stage 3 Install at $500. Intense said its not worth getting retuned with a new exhaust system.

all i can really say is find someone with hptuners pay the $100 or $150 dollar credit you have to pay for you vin number and tune away, the problem is you have to find someone that has hptuners. PM djt81185 he knows alot about this stuff.

I have the HPtuners software. I could go right now and do anything i want to it. I just dont know anything
