Guys,

I would like to know how a muffler delete + Fast Intentions Resonated test pipes would sound like.

I have a 2013 G37s with a muffle delete looking to add the test pipes. I've been searching some video clips but couldn't find any.
I'm happy with the muffler delete but I would like it to be a little more mean aggressive deeper sound.

Also how can I avoid getting the CEL on ?

 

There's several videos on YouTube showcasing how loud that would be for ya. Avoid the CEL with o2 sensor elbows or extenders, easy and cheap.
