Good to know that you found a mechanic to put it in. Got the exhaust covered already?

Yea, me too! No, the exhaust is the last large piece of the puzzle. I do however have the photo's of the one you showed me to work from. I have all the elbow's and pipes bookmarked. I am waiting on a part number for the muffler, from a Camaro I think from Olejoedad.

So which muffler you will use? (brand)

I am going to use...... who am I kidding, I do not have a clue yet

I know I want it as quiet as possible. It seems with the layout options available, there is absolutely no way to make it really quiet. So no matter how quiet I do make it, it will still have enough rumble I am sure On your advice, I am going to wrap the muffler for that added reduction of the noise / resonance. I am still completely open to suggestions for the quietest muffler out there, with the single input on the top, and 2 outputs on the bottom of the muffler as shown in the photo below.



I was wondering if I extend the gray wrapped bend, so it extends all the way to the left tail pipe (Picture that 180 bend being right behind the left exhaust tips), if I would have the ability to put a small CAT inline to dampen the noise a tiny bit further. Is there anything that would prevent this, the cradle ect in doing so?

The muffler in your picture is a Magnaflo.....

That picture sure looks familiar!

It should, it's yours Did you find the part number for that muffler yet by chance? Alex had sent me a very similar picture and I posted it. You saw it, and suggested the one above. It is very similar, but a little bit simpler to make (Total of 6 welds / connections). Alex's has both outputs on the same side, adding a little more height to the setup, as well as adding more bends and such to make it (16 welds / connections).

Here is Alex's setup: Do NOT get me wrong, it is an excellent setup, however the one above is a bit easier to make:


Still wondering if I can extend the pipe to fit a small CAT inline, like I mentioned 2 posts back.....

I think you missed my reply on previous page. See below. Trust me. Nothing will sound like this Magnaflow. But I understand your point. Exhaust is a very personal but critical part of a car. On a custom one like this it is more critical as it is something that you cannot change cheaply or quickly. Knowing how detailed you are, If I were you I would try to listen to both setups and then decide. Just a recommendation Oh, and there's no space there for a CAT.

I am loving this whole mail delivery from Amazon on Sundays thing! I ordered stuff Friday night, and most of it got here this morning. The rest will be here tomorrow.

I have been keeping track of what this swap is costing. There are certainly a lot of things on my list that others would not need to purchase, and other things that you need that are not on this list. It is a rough idea though, for price, as well as where the parts were obtained from for someone preparing to do an engine swap.

John,

Here's the exhaust/muffler info, should be the same as above. The muffler is a Magnaflow for the 3'rd/4'th gen F-body (camaro/firebird)

http://www.magnaflow.com/products?partNumber=12267

I'm using the 3" in, 2.5" outs. They have a couple different ones with different finishes.

Bob
