So, I just picked up a 2007 MCS and I've started to mod it slowly. I'm looking to get a turbo back exhaust either NM Eng or RISS Racing, both have caught my eye. Both systems appear to be very similar:

Since I don't know that much about either company, I was hoping the MC community could help and give some advice, educate me. I am a little budget minded and the NM exhaust is $1,100 and I've seen the RR as low as $700-$800. I can use the money I save buying the RR exhaust and get springs and go ahead and buy the rear control arms at the same time. I plan to get the springs and control arms eventually, but the RR exhaust could speed up the buying process. I'm willing to buy the NM, but since I don't know too much about them and the gains I'll get is hard to justify spending the extra $400. As I would imagine the gains would be about the same for both exhausts. Quality of the product is important to me as well, both look like good companies and products, but I've never dealt with either of them.

Mods so far: ECU tune, engine bushings, H-sport rear sway bar, Forge blow off valve. The final mod would be a front mount intercooler, intercooler piping and final ECU tune, done in stages over a year or so.

Thanks for everyone's time.

 

Both those exhaust prices are for downpipe back ( basically cat backs ). Not sure if that's what your looking for, but thought I'd bring it up since the thread said turbo back.

Also most DP backs don't gain much if anything, so most people just make the decision based off sound, quality, and looks.

 

Riss racing is no longer in business.

 

I meant DP back.

And if RR Racing is out of business, guess I'm leaning towards the NM DP back exhaust.

 

I've heard a ton of problems with the riss racing cat-back exhaust. (leaking, not fitting right, etc.) I have invidia cat back, and it sounds deep and great, also is very cheap. (I got mine for $665)
Just my 0.02

 

That's easy with RR company problems, go with the NM exhaust.

And like Mike said don't count on HP gains from an exhaust without a downpipe.

 

Way, shout out about YOUR DP. You advertise yet I've heard nothing about it.
