will this hinder mpg? will this also cause the black residue on your bumper from the exhaust? will this void warranty?

it may cause the residue depending on your exhaust.

almost any performance mod would hinder your mpg, but a test pipe may not really be that noticeable. What other mods do you have? tuned? IF maybe you got it tuned to ensure that you have a good A/F, you may even get better gas mileage.

Only if you are running rich, and yes, it will certainly void your warranty.

it's an easy install..you can change it out if you have any warranty issues.

Good idea. Easy to swap over.

2007 = DBW not sure if they have the CEL fix on it yet or not. Would be worth your time investigating before "throwing" $$$ out the window
