Mufflers for Hedman Hedders?

Hi all. I just finished rebuilding my 258 and I put on dual outlet Hedman hedders in the process. I was wondering what would be the best sounding exhaust for this engine and these hedders. I was thinking about putting on glasspacks, but a friend told me that he heard glasspacks on a 6 cyl before and it didn't sound good at all, plus he said they have increased backpressure on the 6's. What does everyone think? Thanx for any advice.

Re: Mufflers for Hedman Hedders?

I would try to get a flowmaster on there. They make mufflers for just about anything, plus they aren't expensive, have a pretty good warranty, and sound excellent. They have different versions to let you choose how loud you want it, I think the Delta is the new one that sounds nice and isn't too loud.

By the way, I'm curious about your headers, how much was everything? Does it allow hookup of smog stuff, or not? What made you go with headers instead of a regular manifold? See, I need to replace my manifold and I'm debating headers.

Thanks a bunch

Re: Mufflers for Hedman Hedders?

Thanks for the suggestion. I'll give them a look.
As far as the headers, they were around $150 but they don't have any hookups for emissions equipment. I have a 78 CJ7 and I really didn't have much emmisions equipment to speak of other than the EGR and the vapor can, so this wasn't really an issue for me. They come with a blockoff plate for where the exhaust manifold attaches to the intake manifold so I guess you would have to do some fab if you would want the EGR to work. I still have my EGR attached but it is just acting as a blockoff and serves no other purpose.
I chose the headers because I needed a new manifold and since I live in Georgia where it doesn't get too cold this seemed like a pretty good option. Plus the headers were cheaper than buying a new manifold. Hopefully I'll get some more HP out of this setup also. I want to keep it dual all the way though, so I have been trying to figure where to run the extra pipe.
