TH headers are it if you want to use the 3.5 THDP. I dont know if Arizona GN headers work with it. Postons headers work with the 3.5. ATRs can be made to work if you are not afraid of a hammer and smack the down pipe real good. Certainly not what i recomned but i have heard of it being done before.
DAMM, I HAVE ATR HEADERS AND I HAVE A THDP IN 3.5 COMING TODAY.
IM GONNA HAVE TO MASSAGE THE PIPE? IS IT GOING TO LOOK LIKE CRAP? WHERE IS THE PROBLEM AT THE FRAME RAIL?? THANKS
GANGSTER, let me know how it works out. If not maybe i'll try n have something made up to extend the pipe out a little more if that's what the problem is. Good question:
WELL, ITS BEEN CONFIRMED. THE SHOP WHERE MY CAR IS JUST CALLED AND SAID THE PIPE HITS THE CROSS OVER BAD.
HE SAYS ITS MORE THAN JUST A "HAMMER MASSAGE"
HES REEVALUATING AND THEN WE WILL FIGURE OUT THE BEST WAY TO MAKE IT FIT.
ILL LET YOU KNOW HOW WE FIX IT.
This is why I sold my 3.5 THDP and built my own with a external waste gate . When it was done and over is still had 65.00 left over from the THDP sale. My home made steel DP cost me 100.00 in parts and welding.
GANGSTER, give me first dibs if ur serious about selling. If I get it to work i'll let u know. I have a friend that custom makes exhaust. Unless u want 2 work something out.
Na, I cant get myself to beat that gorgeous pipe up, If buick time wants it for what I paid its his. I put the 3" set up back in today and welded the dump pipe back on.
ever have one of those days when you say to yourself;
"I should have woke up and threw my wallet out the window and went back to sleep"
Thats how my last 3 days have been.
