What's going to happen to my car (fuel consumption/CEL/HP/TQ) if I do berk technologies muffler delete?

ATL BRZ · 12-15-2012, 11:48 AM

You'll see a slight (7whp) gain and more sound.

No noticeable effect on mileage, no CEL's.

I didn't feel any power gain. Honestly its slightly louder (sounds great to me) but don't plan on feeling any different.

My mpg stayed exactly the same (no surprise)

No Dyno's to prove anything but my butt dyno says "hurry up and give me boost"

Did you reset your ECU when you installed? It's only an 7whp gain that DSport measured so it may not be that noticeable via a butt dyno.

I worried about the same things until I got mine. There are literally no downsides to adding the muffler delete. It makes the car sound brilliant, very slight increase in power, weight loss of 25lbs, and it takes about a half hour to install.

Great info! Thanks to all! Ill post here pics and install steps.

I've got a single exit. The mpg did drop a bit(2-3) but Im not sure if it's from the pipe or because my new driving habits. The sound brings out the hooligan in me unfortunately. Hp doesn't really matter because this car is slow anyway but you should find it to pull slightly harder from 5500 up.

This is with the single exit from berk and injen cold air intake as you can see I it pretty decent gains

I got the Berk. No affect on mpg. Feel a difference in top end for sure. Sounds amazing. A little loud in the cabin but I'm used to it now.
