Gee golly willigers, i better not let my engine breath in any air at all.

What temp do you think ENTERS the motor in the first place?

The exhaust gasses leave the combustion chamber with such force that the only time reversion could even take place is under a lift throttle condition. And even then the throttle plate is closed, and the motor is pulling vacuum anyway.

Show me one car where they took their exhaust off and their motor failed from reversion and you have conclusive evidence.

I rode around for over a YEAR OPEN HEADER REVVING TO 10,000 RPMS ON A STOCK BOTTOM END GSR.
gsr hummm does it have 1000+ horsepower?

You have your opinion and I have mine i will stick to mine as I pay/buy all my stuff so i do what keeps it running..Not to mention leaving it open header makes more and more people laugh at you and call you a ricer , clean your exhaust tone up and try not to piss people off because your 120 hp toyota celica has a open exhaust...Wanna go fast? get a Big block with 750+ hp and then run it open exhaust . These damn ricer makes me wanna run them over with their open exhaust.
