H3X
 

2007 H3x 3.7. I want to change the exhaust to duel and who has the best , I would like to install a 1" spacer kit and cold air intake? this truck needs something more. Is it worth $1,000.00 (exhaust ) $150.00 (spacer) $400. (air cleaner) ????

It will be noisier, that's it.

Shouldn't this be in the technical disscussion? Anyways, the intake will help a little, depending which one will also make the engine noisier. I have the K&N intake, it helps, but is noisier since you have to remove the resonator when installing the intake.

Use the search tool in the technical section for intake, exhaust, spacer. You would be surprised how many people have already talked about all of these items.

The spacer i would not waste my money.

Re: H3X
 

Most spacers will emit a high pitch whistle. Could be rather annoying.

Re: H3X
 

I get no whistle sound

Re: H3X
 

Do you have the spacer? Which one did you get? Can I assume that you didn't notice any performance improvement?
