Pretty much any of the sponser's will have them ie tbyrne,arizona speed&marine(ASM)those are just a few to name. BTW i have the ASM's and i love them i am running stock 3" ypipe but soon to be replaced by a custom x pipe setup. As far as y pipes go magnaflow makes one but it cost around 600+ for the y pipe i believe its about 2.5" not 3". I would have one custom made if i were you to fit your application properly. Where are you located??????

 

heres another vote for ASM but i also here a lot of good stuff about TOG and thorley headers just to give you a selection to go on good luck have fun

 

Located in central kentucky, Richmond..
i didnt know magnaflow had one i have to check into that if i cant find anyone to do a custom fit one.

 

looks like the guys here got you covered:

FLP's
ASM
TOG
thorley

glad to here you are not interested in shorties

 

sounds like theres a lot of options i hope i can get some of these headers found thats in my price range..

 

Quick Time Perf. is apparently creating a new and improved long tube y design header. Might be worth sticking out for
