Hello,

Has anyone on here used the ARH long system (headers and X-pipe)? I'm interested in performance, but I'm actually more interested in fitment! If you have installed this system, how did it fit?

Thanks

I had ARH 2” catless full system on my 2015 A8 Z07, I honestly wasn’t too impressed with the dyno difference sense I did a AFE intake and tune prior so the before and after really wasn’t too much. This time around on my 2019 Z06 M7 I decided to use NorCal’s Main pipe delete and corsa mid pipe so I didn’t have to do a tune to void warranty.

Also fitment was great and they sounded awesome on the stock NPP. I did get kicked out of the track for noise violation at Portland International Raceway.

Thanks for the reply and advice! Was the fitment and sound good on the ARH or are you talking about the other setup?

Does anyone else have another view on the ARH long system (headers and X-pipe)? Thank You...

I cant speak on my current '19Z; but on my '02 Z, I had ARH long tubes and x-pipe and the fitment was 100% perfect. And I mean PERFECT. The quality of ARH is absolutely top notch and I personally would not even consider another brand after my experience with them. If I decide to do headers on my '19, I can guarantee they will be ARH.

fitment is perfect and we install probably 5-6 sets a month.

Thanks again to everyone that replied. I have made my decision!

ARH is top quality stuff.
I got 2” primaries and 3” collectors and had them ceramic coated, headers fit great.
I got the catted x-pipe and the cats interfered with the belly plate. We had to use spacers to lower the belly plate. Hope this helps.
