Do I have to remove the front bumper to install this piece?

 

Not necessarily....It would make life a little easier though.

 

lets us know with the results im debating when i get a evo to go with a busher or ams...im looking for lower end torqe...basically quicker spool i think factory hp is fine with a drop in and mabe a tbe and tune....and you cant forget getting rid of that stupid spare tire and the cheap lifter thingy....

You don't need to remove the bumper. Just the undertray.

 

the upper pipes do nothing for performance. There more for show thasn anything else

 

So you've done a test on them then.
