Huh, seems like a lot of people always recommended the CPE and Cobb. Obviously quality pieces with a proven track record. Unfortunately, it seems you pay a lot for that reputation and brand names.
It also seems that the PG inlet or combo is pretty hit or miss. I have read people say no issues, works great and you can't beat the price. Then I have also read statements like Tunersteves saying quality is lacking and there are plenty of out of stock and customer service horror stories.
I don't however, hear a lot (good or bad) about the Corksport combo. When I was looking a few weeks ago, to me it seemed like a good compromise. Fairly well know company for Mazda performance with a decent reputation. Plus, you could pick up the combo Inlet/TIP for about the same price as just one piece from CPE or Cobb. I went ahead and ordered the combo.
However, I am a little nervous that I haven't really heard of anyone running the CS. When I first ordered it was on backorder for about 3 weeks, but they were very upfront and provided good communication. Just got an email yesterday saying it shipped so should be here in a few days. I guess I will let everyone know my impressions as far as quality and performance once I get it installed.
Yea, I know that was a little OT as far as matching to a CAI, but figured the discussion has moved to TIPs in general, so thought I would throw out my 2 cents.
