need opinions on these exhausts. Getting rid of my rmr for either of these HKS 30th, Turbo xS, or thermal . Leaning towards the Turbo XS.

 

I have the thermal research exhaust on my evo. Its a little louder than stock. The quality of the exhaust so awesome. I would recommend thermal.

 

I've also tried to get feedback on the Thermal exhaust. Not that many people are using them(I don't know why). The people that do have it say that the fitment is awesome and the sound is not loud. I believe evo8ya has a picture of the exhaust.
