Okay so right now Im trying to pick the best Header/Y-pipe setup there is for my 99 max. I already know Cattman is as good as it gets when it comes to y-pipe but i dont know about the headers though. Im choosing between the OBX header/Y-pipe, Stone racing header/Y-pipe, and then Cattman header/y-pipe. I just wanted to know what you guyz thought. Please if you have these products put in your input. This is an expensive mod and I wanna make the right choice. Thanks

 

get cattman, obx has fitment issues (thats what i have), and i've yet to hear of any real gains from the SR headers, remember this when modding: YOU GET WHAT YOU PAY FOR

 

If I remember correctly I heard someone mentioning that hotshot header might release a header for the 4th gen. But, lately I haven't heard any updates.

 

stay away from OBX

 

i would call up brian catts of cattman 1-800-759-9930 they will give you his direct phone line he will answer any questions about y pipes or anything else

 

Thanks for the info people. Really appriciate it. If theres more opinions please post. So far I think Im going with Cattman Header/Y-pipe. Im also wondering if theres a big H.P. gain difference from just having tha Cattman Y-pipe alone, or haveing both Cattman Headers and Y-pipe. Please let me know. Once again thanks.

 

cattman... if you get a y-pipe expect maybe around 15 hp, with headers... i have heard gains of 22 hp... you get what you pay for

headers not header... i stood corrected...

 

Stone mountain headers are working fine for me.

 

Unless you're planning on going S/C'd, the gains from a y-pipe should be sufficient. Adding the headers only add like 2 hp over that of a y-pipe alone, and when you think about the price, it just can't be justified. This is what I heard about n/a cars. But as I said, if going s/c'd, you might wanna get that out of the way.

 

Okay so O.B.X is completly out tha picture. I pretty much know Cattman is top notch for maxima tuning. But you say Stone Mountain headers do you good. Did you have to modify anything as far as o2 sensors or was it straight
bolt and play? Did you feel a big hp increas? Please guyz give me some feedback on the S.M.R headers. I havent heard bad things but I havent really heard much period. Thanks

 

OBX...I saw a lot of those on ebay for really cheap prices...and I was instantly like "no way". I would stay away from them, I have no expierence with them but just from price I wouldnt put them on my car. At least they are shiny tho :-)
