Def keep it on unless you want mitsu to void your warranty

But on a serious note I would keep it on. The clips can be a pain but its really not that hard. A very small flat head screwdriver is your friend My undertray is on for the most part. I had to cut out some of it to fit my intercooler and im also missing a part in the center for my external dump. But the rest of it is there and im glad it is.

 

I didn't have a choice really, I went and rallied in the dirt and ripped it clean off, and I mean it came off perfectly lol

I just got out picked it up and stashed it in my garage and never got around to dealing with it lol

 

Lose it. I've been without it for 2 years and am so happy I ditched that piece of crap. I've done track days at >100mph. Unless you're Tommi Makkinen, you won't feel the difference.

 

yea the undertray could be a b****. but i still have mine on, just didnt put all the screws back on. i just put them on where they wont leave the undertray hanging

 

+ 2 I even noticed my gas mileage get a little better.

 

i would leave it

 

Does the Beatrush undertray fit with an aftermarket 3" downpipe? I've heard both sides that they do and do not.. Can anyone please confirm?

 

I think it depends on the DP, works on mine, but i have heard it not fit before. There is a good amount of clearance on the bottom so i would imagine that most DPs would work.

 

I junked mine. Got fed up with dealing with it every time I worked on it. It makes things so much easier.
