Does anyone have any info on installing test pipes?

Can this damage the car in any way if they were used every day?

What kind of gains can you see in an auto? Anyone have a dyno on this?

Hoe does this affect backpressure / torque?

Any insight would be great!

 

there won't be any damage to your car but it will certainly demage the environment... also if you breathe that exhaust fume it will certainly do damage to your body as well. also if you get caught driving with out a cat, not only will you pay a hefty fine but you will also do jail time and community service. i don't think gaining 2~4hp is worth all that trouble.
