AR design downpipes review

I have recently installed my AR design catless downpipes.

Result is great, I wasn't expecting that much sound differences. Sound is just like how I want. I was planning to install an aggressive exhaust but I don't think I will do it after install this. It gives pretty much what I needed.

Weldings are almost perfect, I don't think that would be better than this.
Fitment was good too, installation took 3 hours and weight of the downpipes almost half of the stock one. Installed in PTunning in Manassas VA and cost me $350.

I haven't seen much differences in performance in first 30mins, but after running with map5 jb4, I can notice the huge differences.

Definitely recommended, I think it is the best money I have spent on my car.
Video will be uploaded soon.

Nice really considering this on my 35iS and keeping stock exhaust with golf-t mod. I am wondering how catless affects pollution levels?

You need a FMIC.

Cats convert over 90% of hydrocarbons, carbon monoxide, and nitrogen oxides into CO2, nitrogen, and water vapor. So they make a pretty big difference.

The main cats are in the x-pipe. The ones in the dp are primarily for emissions control during cold starts. Once the engine (and main cats) is warmed up you pass every co2 test in europe.

It affects pretty much I guess, I cannot provide you the numbers of "hydrocarbons, carbon monoxide, and nitrogen oxides into CO2, nitrogen" but
smell I get in the cabin tells everything. Not really annoying but noticeable.

As said, there are other cats in exhaust, CEL light didn't turned on yet, but not sure if it will pass or not. I got wedge dp fix for 60 some dollars, so if it doesn't pass I will use it.
