Does anyone have them do the rust or Crack over time , just would like to hear some reviews from people who have them, also would you recommend high flow cats or no cats at all I'm looking for super loud as well

A bunch of the local BMW guys have them, and they seem to hold up OK, for the money. Keep in mind, theirs are about $1000 less than a lot of other guys', so looking at it that way I think they're pretty good.

I can get headers and mid pipe for about 2500 than anothe 800-900 install and 250 for dyno tune

$250 seems crazy low. The rest seems about right.

AP at least in the E46 M3 community, has been known to experience more cracking than other brands. Don't know if that carries over to other AP Header designs or construction methods/materials, but just be aware.

I already had car tuned for 1000 at same shop ,every time you add a part they only charge 250 to tune

$800-900 to install headers seems crazy high, I had mine installed for $450.

beaststunt

really wow , I'm scared to let just anyone put headers on my car, I go to this shop in cherryhill nj, I trust them just because I have seen them work on other c63 ,Lamborghini, Porsche, and alot of other high end cars

Oh, I am in Los Angeles and only trust one shop for exhaust too. They used to do all the exhaust work for CEC Wheels so they know their stuff.

I guess East coast vs west coast prices?

Got the full exhaust installed a while ago. Headers as well as their valvetronic mufflers. Only issue I had with headers was the fact that the 4 exhaust runners slip on to the collector for each header. I would prefer that they were 100% welded. Another issue is that I think because of this might have an exhaust leak. Not 100% sure. Starting to get a strong exhaust smell when sitting inside car with my window rolled down . Might just be me tho. When I tried to ask AP / Vivid about problem on the form I received no feed back or recommendation and just got ignored . On the plus side...the valued mufflers are a must for cold starts and driving around the neighborhood. When you wanna sound Nascar crazy loud...open the valves and enjoy the sweet sound of this beast!! Been thinking of swaping them out with MBH headers soon. Absolutely zero bad reviews on these headers.
