Your right I just looked again because I swear it was that price. I was looking at the N54 ones. And it makes me wonder why is the N54 about half the price of N55?

Because the F10s cost more so there's an assumption that we are frivolous with our money.

Okay guys I just sent AR Design the downpipes today so production for these should be coming soon.

I have no idea what the pricing will be but it's not going to be 3 times RSI. RSI is selling for $595 right?

That's what I thought! Thanks for making sure tho. BurgerMotorsport sell it for $599. I just wanna wait until AR to come out and will decide if the price difference is not too much.

Try google! Real easy to type in AR downpipe and get results. Or you can try reading a few of our post and see where they are available.

guys, what's the difference between Catless and Catted? I'm assuming catted means it has all the content of a cat inside and if that is the case, why put one in if it does not help performance?

In California it is illegal to drive without a Cat, but some will take the risk in order to gain performance

Looks great so far. Can't wait to see those nice TIG welds all the way around though. Did they tell you an ETA? To consumers of course.

Unless they have a CEL fix, I'm 100% sure that is going to throw a CEL light on our dashes.

I also prototyped other downpipes from RSi that had two, 100 cell race cats setup in line.

I'll have mine back next week and I'll ask when the eta is for them to release as well.

With the JB4 V2 I think Terry resolved the CEL issue with the downpipes.

I don't think that answers his question. I get that there is a benefit of switching out the stock catted downpipe with a catless to improve performance.

The real question is, why buy a catted downpipe to replace the catted stock downpipe?

(I'm glad the question was asked. Because, I was wondering the same thing) What is the benefit?

Also, has anyone concluded if the installation of a catless downpipe can be successfully accomplished without causing the code alert (whatever you call it) from appearing on the dash display?

I have the RSi catless downpipe and the JB4 S2 and it doesn't show a CEL.
