ok guys i have a huge delema. im planing on having a 400s/b built with around 575 to 625 hp. if i do a roller motor the guy who is going to build it for me told me it will rev to 7500 possibly 8000 rpms. my car is lowered and i have the spohn trans x member and driveshaft loop. im looking at stainless works for my headers. they are full length but hug the floor for ground clearance. everything from there will need to be done at a shop. what do i have to go with id like to keep a single exhaust for clearance but i know the engine will not allow that. any input from everyone will help alot!...thanks guys.

 

If you actually get that motor into your ride, you will NOT want to do with a Y-pipe style exhaust. It's dumped duals at that point, or don't even bother =P

 

i doubt i could get away with 2.5 inch duals huh? i dont know much about the exhaust when it comes to displacement and hp. i plan to use stainless works chambered mufflers if possible

 

Mufflex has a couple 4" exhaust, they also have a Y pipe if you use hooker long tubes

 

Have you seen today's post on "true dual 3" at last" ?????
Good luch I have a BBC and been trying for years to come up with a suitable answer

MY collectors sit below side sills !!!!!!!

 

I love my Mufflex 4 inch exhaust and they say it will support up to 600 horses.

 

looks like guys are having a hard time fitting the mufflex Y pipe with a spohn X member. just run open headers.

 

I just looked at the stainlessworks website----they dont make a header for the 3rd gen f-body-----only gen4.....unless you have seen somthing thats not on the website yet

 

i was waiting for someone to say that about there site.....your right they are from hawks third gen. stainless works makes them only for hawks.
