However, i'm getting tired of AR trash talking all the other DP vendors(who unfortunately aren't here to defend themselves) and then offering no evidence to support their claims. Show a graph detailing back pressure or flow and ARs being superior.
Like i said, if im wrong i'll be the first to admit it and it will provide actual data for the platform as a whole.
AR: put up or shut up.
I had AA. Rubbed from day one. Tried myself and took it to 2 shops to realign. There was no way to prevent them from rubbing. This might be because I was in the GB for the first sets out. So if the fitment is good now then that's all that matters. For the record, my AR pipes fit on my first try and never rub. The mouth on the AA pipes was also so wide that it took a pair of pliers just to close the downpipe clamp...

Like I said, this may have been fixed. If so, I apologize for speaking against AA.

Ive sold a few AA DP's since I became a dealer and Ive heard no complaints. They've been in the business long enough to know if a product is good, and represents their stellar reputation. Perhaps some of the earlier models might have need a tweak or adjustment but as far as I recall they have revised them since then.

A majority of DP issues usually relate to install error. Keyword, usually.
This might be true. I was in the first batch to receive my AA pipes.

I was in the same boat as the OP. I did my research and I was undecided between MS, AA and AR. I only have read good review for all of them but AR was my last choice due to being pricey. Thanks to Black Friday sale I got a pretty good price for the AR with Mike@N54tuning.com and I ordered them 2 days ago . Another point to consider with the AR is that they have a very good re-sale value. I seen used AR sells quickly in the classified section. Just my 2 cents.
