I'm going to post some pics of my 2 1/2inch duals. I used the hedman S-extensions, 2 1/2in straight pipe and moroso spiral flow mufflers. Headers are Hedman 1 5/8prim. and 3 in. collector.

 

Looks like plenty of clearance, i wish mine tucked that good.

 

here's a sound clip of idle

 

I just installed my headers yesterday and I was wondering what I could get to make it around the tranny cross member. Do you have a part# for the s pipe and does it clear well ??

 

The part number is HED-18700 from summit racing. They are the ball and socket type. They do carry other collector styles. The s-pipes come right under the crossmember. From there I ran the straight pipe. Someday I'll use mayber a smaller and shorter s-pipe to tuck it up little more. Right now I've got about 4in of clearance.

 

Westman, what did you use for the powersteering bracket ?? I dont want to hack mine an dmake it look like crap is the a new powersteering bracket you can buy to clear the larger primary tubes ???

 

Actually what I did was scrap the entire serpentine system. I swapped a big block into my 79 GMC and just used all the accessories off of the old small block. And everything fit pretty well. My biggest problem was getting the damn alternator bracket to work with the vortec intake. After trying three different kinds I finally made my own.

 

Just use threaded rod for that header hole and run 3 nuts. One nut against the header, one right before the bracket and one right after the bracket to tighten it against the first nut. Works great on all the serp. cars that I've put headers on for people.

 

Just outta curiosity, do you have a pic of that?

 

im running the same setup..

 

Here is some photos of BBC mod.. may give you some ideas..

 

I am running regular v belt pulley's so I dont think I can to that. Any other suggestions ?

 

i v-belt pulleys as well, i didnt have a problem with the power steering bracket, although i run a march bracket.

 

Thats the thing I tried to find a new bracket from hedman or hooker but nobody makes a cheap one. Everything is like $80-$120.

 

More pics finally

 

How loud is your car with those mufflers ?

 

Um.. You could say "Very Noticable". Not as loud as the glasspaks on my truck, but much louder than my single aerochamber.

 

Nice job!
