Default exhaust system question

I have a 77 L82 and need to replace exhaust system and was thinking of headers and going out the back. My question is would that help my hp and how much. And I really don't want it real loud. I also don't know what mufflers to go with. Any help would be appreciated. vince

Headers and a nice free flowing exhaust will help with TQ and HP. But dont expect to see huge gains from that alone. You will see bigger gains from a top end package, which will reguire a free flowing exhaust. so you need to get a plan and decide what you want and where your going to end up?

I am just coming off a 1006 468 BBC in my 77 camaro and stepping down to 360 HP 350 so get a plan and stick to it or it will get out of hand fast.SBC for the vette.

Yes. Many like Dynomax Super Turbo.
See what many refer to as my Exhaust topic.

thanks for the suggestions but should i go headers into one back out to two and two mufflers or two seperate all the way because the cat was removed before i bought the car and they don't do emitions testing where i live. It's a stock 350 L82 and I would like to get the best performance possible. thanks Vince
