New 07 Hummer got Questions....

[Adrianhummedup]

Hello Hummer peeps!! New to the site and have a few questions I hope I can get answered in here.

2007 Hummer H3 Black on Black....

1. Throttle Body spacers(Poweraid Spacer), are these a good buy in regards to throttle improvement and gas mileage? Also will it void my warranty if detected?

2. Cat back exhaust, or are there any other exhaust you'd recommend besides Magnaflow?

3. Airaid Intake System, will this void my factory warranty as well and are the gains noticeable? I'm looking for a tad bit of low end throttle response and a tad bit better gas mileage not much its a Hummer...

no voids but the spacer is a waste of money, the air cleaner is not worth it (I did it) lets too much in in my opnion if you off road. exhaust is the best for the buck but it get noisy. No voids but be careful who does the work. If they f-up the delaer will not fix it for ya.

Save your $$ for a V8 Alpha

Thanks for the replies peeps I appreciate it. So from the sounds of it go with just the Exhaust and call it a day. The V8 alpha sounds awesome but I just got my 07 1/2 they say three days ago. I do like the change of the window controlls prior to the previous 07 and 06 models.

I'm digging the Toyo open Country on some 20" x 10" Helo black with polished lip rims. Any comment on the road noise from the Toyo Open country? Sorry I'm going from a VW GTI modded out to a Hummer H3 so I'm a super newb when it comes to GM products and espcially Hummers....

seach the forums and you will find your answers young one

I'm using Corsa exhaust system on my 06 H3. Noise at cruise is minimal so it's okay as daily driver.
