Our long tube step headers fit right in the C6.

Well the numbers are in.

With the Vortex ram induction 349 to 353 RWHP

With Vortex Ram Induction & BPP Long Tube Step Headers with off road X-Pipe 369 to 374 RWHP

Wide Band A/F was at about 11.90

That is 21 RWHP gain or about 26 Flywheel HP.

By the way this is an auto car.

Our next test would be with street X-pipe.

One note our fuel trim #s at idle were +18 and at cruise +9 which shows we are running leaner.
