Here is what I plan for the system, with some pipe in between the H-pipe and the mufflers. Probably dumped, might have tailpipes added at a shop, straight out the back. Look good? Or do I have it all screwed up. Remember, I am dropping a 355 in, ultimate TBI mods will be done.

As for the 355, have fun with that! =]

 

Crap, I didn't know that. Ok, here are the parts:
Headers; reducers; h-pipe; mufflers. There will be two mufflers, of course. Headers>reducers>h-pipe>pipe to back of cab>mufflers. Maybe tail pipes straight out the back.

 

I've always loved the way tailpipes look straight out the back; it's how mine are, after all. =]
I like the headers, but I personally think you'd enjoy larger piping. 2 1/4 isn't very large; I personally would go with 3", but that's just my taste; yours may be very different. I'd also recommend a different muffler; I'm a fan of Flowmaster, Magnaflow, and Borla; but again, your tastes in tone may be different.

 

Flowmaster is ok. I have had dual glass packs on a couple of 355 equipped vehicles before. I read on another forum I am on (http://www.fullsizechevy.com) that the Dynomax is a good muffler. It was recommended to get it, or the Magnaflow.
I like the way the ram air 350 Firebirds and Camaros sound, the ones that have exhaust work done. A guy around the corner from me has a Firebird, ram air, headers, and side pipes. I think it is straight pipes with no mufflers though. It is loud, and has that rasp to it when he shifts. His car sounds like it has some mods to it though.
My oldest bro has a cat-back Flowmaster dual package on his Mustang, headers too. It sounds good, and I can get the exact same set for $100 BNIB from my BIL. It is the Delta 40 set up. I was going to do that, but decided to get Dynomax instead.

 

Any namebrand muffler is a good muffler.
I'm a big fan of the Flowmasters tone myself.

 

Should I go with dual 2.25 or dual 2.5 pipe/mufflers? It is only $8 difference, for the reducers, h-pipe, and mufflers. Mild 355, more stock. Plan on future cam upgrade though.
Also, will I need a new chip, or will a stock 350 chip work? If it will run decently with the stock one, that is ok for now. When I do the upgrades later on I can get a chip then, if that will work.

 

2.5" is what I have on my 350.

 

2.5 it is then. What about the chip?
Also, can I get the electronic spark control module used, or should I buy a new one?

 

Buy a new Esc module, and I also have 2.5 good setup! I have that rasp when I shift also and all I have is a Cat and two Flowmasters!
