It is probably easier for you to just pull the triangl out than to try and work from under the car. You have to slide something in between the triangle and the bumper cover to get the tabs to release, then it just pops right out. I just pushed out the block plate and then forced the triangle out, but I probably got lucky that I didn't break any of the tab holders.
Do you just plan on doing a wet lay-up or are you going to bag it? I made mine in a hurry and jisy did a lay-up, but bagging it would have finished it off better.
You will be exhaust limited after doing this. I did the dyno runs on it this weekend and couldn't pull much more power out of it in comparison to the snorkel delete. Not a bad thing, it just means that we are sitting on the same power as the name brand CAI's
