Hit up m750 from NESIC. He's got some on his GC RS and seems happy. I was just in his car last week.

Very good headers. We've run them for a couple years now and have no complaints. I'm not convinced the H pipe is even part of the flow. I can't feel any openings when feeling around with a coathanger.....

Upsides:
Bulletproof
Make as much power as anything out there
Sound unique but not raspy

Downsides:
Mild steel construction
Weight
Stock cat longevity
Requires non-stock midpipe shape

I've been reasonably happy w/ my MRT. Though, I've had an exhaust leak the whole time I've owned it, and a CEL. It depends on the price. I got it back in 2001 for around 450 for the whole thing. It was a steal. What I liked: price, it sounds pretty good, equal length. What are they going for now?
Here are my recomendations:
1. Get it coated, it won't hold up in snowy salty enviorments.
2. Skip the muffler, either get a wrx one for free, or use another premade rs muffler.
3. Have it professionally installed, but, make sure they know that they can lossen a wire tie that holds the o2 sensor wires. They should not need to cut splice any wires.

I got my MRT system in the same group buy that m750 got his. He and I both had ours coated by www.airborncoatings.com in Hartford, CT (similar stuff to Jet Hot, just a different brand name). I recently discovered two cracks where the cross-over pipe joins each main tube and had those welded up (posted here about it a couple weeks ago). All in all I've been very happy with the system. If you search you'll find some dyno graphs I posted way back when I first got the system - a dyno proven +14hp at peak, and something like +18hp at redline, with no loss of low end.

The muffler itself certainly isn't anything special. I just ordered a Stromung dual tip to replace mine - the MRT muffler is fine, hasn't rusted through or anything like that, I just want to try something different.

Storm, how much of a gain did you get with the track pipe welded on? Is the MRT's cat that restrictive?

It was used for testing on a SWC car. Mid pipe was a short section tuned to the engine package. It was eventually replaced with something a little lighter.

Thanks, m750! I needed to know that before I waste money on a test pipe I don't need.
