Does straight pipe hurt your engine?
Straight Pipes Can Damage Your Engine. A street vehicle should not be equipped with a race car-style exhaust system. Straight pipes, for example, can increase exhaust gas velocity. This will reduce engine performance to below 2,000 or 2,500 RPM and make your vehicle slower to launch from a stoplight.
Will my truck pass smog with headers?
Will aftermarket headers cause my car to fail the smog test? Unless the aftermarket headers you purchase and install have an EO stamp, meaning they have been tested by the California Air Resource Board and been issued an Executive Order number, yes they will fail the smog inspection; as a tampered emission component.
How much horsepower does a cat back exhaust add?

Can open headers damage your engine?
Will Open Headers Damage Engine? Open headers will not cause engine damage if you get a tune and fix the air/fuel ratio. Without tuning, open headers can significantly tweak the air/fuel ratio by introducing more oxygen in the combustion chamber.
How much horsepower do you gain from straight pipes?
Both muffler delete and straight pipe can provide minor horsepower improvement (5-10 horsepower, depending on the car). Power gain should be more noticeable on higher RPM.
Do headers fail emissions?
Well-Known Member. Catted headers technically WILL NOT pass emissions because they are not 50 or even 49 state legal since they have been moved from the OEM location. Now, some tuners can set the tune in such a way that when connected to the scanner for the readiness testing they can get you a "PASS" reading.

Does a Flowmaster exhaust add horsepower?
Flowmaster exhaust systems can add about 8 horsepower (about a 10% gain) to increase the performance of your vehicle. The reason that a muffler will help increase horsepower is that it decreases air resistance and makes it easier for exhaust fumes to exit a cylinder and the air flows better.
Do I need a tune for a cat back exhaust?
Cat-back exhaust systems affect the region of exhaust after the catalytic converters. ... They may let more sound flow through, but CB systems do not affect the aspiration of the engine. As a result, Cat-Back exhaust systems do not require an updated tune.
What can I put in my gas tank to pass emissions?
