Exhaust questions.....

[SuperchargedB87]

I want to change my whole exhaust to 3", my question is what kind of 3" cat backs are out there. I don't want to start any trouble, but I know Mac makes one, but I want to stay away from Mac. Does Borla make one? Really all I need is the flow tubes and mufflers, because I can just use turn downs after the mufflers. Any input would be appreciated.

Dr Gas sells 3" flow tubes and 3" turn downs as well. Then you can pick the 3" muffler of your choice and have it all installed. Are you sure you have the HP to need 3" pipes? You know you might lose TQ right?

Does the muffler have to be off set still if you just run turn downs? I always ran tail pipes. As far as horsepower goes that is why I want to change to 3" exhaust and 1 3/4" headers, my new combo makes alot more power and revs alot higher, so I don't think the 2 1/2" exhaust is any good for me anymore. Also I was thinking about the Dynomax bullet mufflers, anyone have any experience with these?

I think the dual 2.5" exhaust is good for upwards of 500 HP. But if you want 3" you get 3". In order for the mufflers to sit where they should (out of the way) I think they still have to be offest but I'm not positive. Depends on how big the mufflers are. Don't know much about the Bullets... race bullets? Loud!
