Headers installed - Page 4 - ZR-1 Net Registry Forums

I got headers installed this last week. They have cats (random tech) and AIR tubes. I drove up to Marc Haibecks to have them done. I also had C-beam plates installed, and got the car dyno tuned. Marc also noticed the shift boot wasn't installed properly, so he fixed that and a loose drivers side exterior mirror. As part of the tune, he re-enabled the shift light and raised the redline to 7,300 rpm.

The car woke up noticeably! It also sounds awesome. There is more burble to the exhaust. There is of course also more noise and resonance. I'll have to see if I get used to it or not. Marc mentioned it seemed to have less resonance than the B&B with headers, and a little more than the '93+ pipes with Flowmaster 40-series delta flows.

Anyway, on to the meat of the upgrade:
