best bang for buck- RP Cat or Unortho pulleys
Guys
Just trying to get a concensus here. My next mod will probaly be one of the two listed. RP cat goes for about $425 with gaskets etc and the Pulley set goes for about $250 uninstalled. I hear good and bad about both. Can't make up my mind. I have the RB catback but if the cat will give me another 8hp(as claimed) then it may win. But I cant find where the cat is giving 8hp or so consistantly. Same with the pullies--some like them and feel the differance--some dont. Would just removing the a/c belt(for track days) be just as good?

od - I have them both installed. Definitely the high flow cat is the biggest bang. As for the pulleys, my throttle response is allot crisper now, and I find that the engine seems to rev easier. I like them both.
I currently have the REV8 installed, but she is coming off this weekend.

One works & the other one doesn't. This isn't a big V8 where you are removing a ton of weight in addition to massively underdriving the components (UR stated they are only undriving like 15%-20%). You are not taking out weight from a massive 15-20 lb. harmonic balancer. The pulleies together maybe add up to a few lbs.

RB mufflers must be damn heavy.

well I've seen a number of dynos that say different, so which ones do you believe?
FWIW, SRMotorsports has their original pulley system on sale for $399, they recently came out with a new wide belt pulley system, looks like it adds two more ribs, they say 25% wider and prevents the water pump from slipping at high rpm

For just the muffler yes, but he whole thing with feeder pipe is 26 lb, my custom one is 9 lb and I bet it's just as quiet on the sound meter, one of their issues is the use 0.065 wall tube (16 Ga) because it's readily avalable but it's really overkill for a stainless system, 18 Ga is plenty adequate for a street system and a race system can get away with 20 Ga, for serious race 22 Ga Inconel 625 will give the best weight/performance
I'm presently building a street version with dual mufflers and tips as a present for a special friend that I think will come in around 16 lbs despite being stainless, should have it done within the next month
