I have an mxp exhaust, injen intake and an oft stage 1 91 oct tune (we don't have 93 where I live). I'm about to buy an OFH off someone but I'm scared about the loudness.
What I'm mostly concerned about is, does it really make a difference in the torque dip?/ does it make a noticeable difference with the stage 2 uel tune combined? I've heard that the difference is so small you won't even notice anything. Is this true? I'd love to hear your opinions.
Also, would an EL hks be just as loud?

All non-stock, catless headers will increase how loud the car is. With a stock exhaust it is still quiet at idle and cruise but noticeably louder when accelerating or on cold start. I don't know where your catback sits on the loudness scale but the Invidia Q300, Perrin 2.5" resonated and the new CSG MXP catback are supposedly not too loud with a header installed.

There is a whole thread on it. Nothing significant changed I believe.

You won't damage anything by not running the stage 2 UEL tune but the car will be MUCH nicer to drive with the stage 2 tune.

I don't believe there is an OTS tune. You will most likely have to read the thread and modify your existing tune.
