i have a hahn cai and a gm stage 1 thinking about "hahning" my car out. for the prices is the charge piping exhaust and down pipe worth it from hahn? and if any one has them already how are the horse power gains for each?

No Hahn is overpriced, I would go with CIA or Dejon CP and ZZP downpipe.

if you are going to do bolt ons, I would get a custom tune for them and ditch that gms1

gms1 is not designed for those bolt ons and you will not take full advantage of any hp gains

I think the hahn downpipe is the best
injen is the best charge pipe
and mpx has the best cat back exhaust
those are my opinions though, but read around and you can come to your own conclusions.

i have no idea how to go about getting a custom tune where do i go and how much as long as i keep my warantee

No aftermarket tune will keep your warranty if caught by GM. Trifecta came out with a "stealth tune" a while back that is said it will not be detectable by the dealers scan tool.

You're going to have warranty trouble anyway, it you put other aftermarket parts on your car. They see that downpipe and start frothing at the mouth because they can blame just about anything on it.

Hahn dp I have fit perfect and I drove a week before I could have my tuner retune and no cel. Worth every penny for quality.

Ive got the catback on my car. Altho i bought the car as it sits the only thing i can tell is that if the car is lowered youll have to raise the exhaust up a tad, as its not been designed for lowered vehicles and may rattle a tad. The sounded is just awesome! Not that loud at idle/cruise, but it will let you know it tere when you open it up!!

i have a test and tune coming up at my local track and only have about 500 bucks to spend what part will give me the most horse power, down pipe, charge piping or an exhaust?

If you only got $500 bucks...I'd say Trifecta tune. Then downpipe, then charge pipe then exhaust...just my opinion though. Tune is the best bang for your buck. Makes a hell of a difference

but the stock charge pipes will die on a high PSI tune
