just installed my stillen headers and noticed the higher noise levels. i also had installed earlier a custom 2.25" catback without a resonator with stillen muffler.

i not experience startup problems...need to crank twoce to keep nmotor running or keep my foot on gas pedal. afterwhich, it idels perfectly. what could be my problem?

You should expect more noise with a bigger exhaust and headers. I noticed that my noise levels went up as I put more mods on my car. If the noise is really loud like you have a leak, check all of the header connections (header to head, secondary to primary, secondary to cat). Also check where the emissions connect to the header and motor.

I can't help with the startup problem, but I would guess once the ECU learns the new header, it'll be fine.
