I'm looking into getting either the catted MRT H or the catted SLP X & was wondering if you stay catted do you need a tune right away like a CAI?

I ask because I was planning on swapping out the midpipe and then going on a 600+ road trip to visit some of my Mustang Brothers in VA.

I appreciate any and all info you can give me.

 

u dont need a tune on a midpipe. If its offroad you will need a tuner or eliminators for the O2 sensors but other then that you won't need a tune if it has cats.

 

Thanks.

 

If I could go back I would have gotten the mrt catted H, that's the only pipe I would choose over my prochamber

 

Why? The prochamber has the deeper rumble

 

It does have a rumble, but so does the MRT.

I've recently heard clips of SLPs with stock midpipe (like my car is now), and then SLPs with the prochamber. I did not like it. It took the agressive "growl" out of the SLPs. When revving it, it sounds way too melow for me, it sounded deep, but didn't have that agressive sound I like.
