I'm running 2 1/2 inch all the way back with a Magniflow muffler. I'm pretty happy with the sound of it. Definitely not the Honda Civic fart can sound!

How did you get the pipes to fit through the crossmember, smoke wrench? (cutting torch). I was thinking 2 inch with an old fashioned glasspack and a monza tip.

There is a chart ( I forget where) that tells recommended sizes to displacement size. For NA motors 1.8-2.4 it recommends 2.25, which is what I have run in the past and has worked out well. Some turbo guys run 3" oval. Your exhaust shop can take a torch or plasma cutter and just enlarge the opening in the x members.

I'm using oval tubing that has the same cross sectional area as 2.5 inch round. It's sold through Spintech. Fits right through the X-Member holes.

Are the stock holes that big?? Looks like 2" will just fit, but not larger. Maybe they vary, or I've spent too much time upside down under the car today.

I'm looking into this as well for my '69 2000.
I have a flex coupling, and I'm thinking of 2" pipe with a glasspack. Hope to find something that looks like the stock "megaphone" tail pipe.

I just fired my car up yesterday for the first time, new header, flex coupling then 1 3/4 pipe all the way back to the stock megaphone resonator. Sounds really good. might leave it for now. Summit Racing sells old fashioned glasspacks by Patriot and bullet style by others. My first Roadster had 2" exhaust and a straight Thrush. Was perfect sound, but the mufflers are collectors items now, were $15.00 back then.
There is an exhaust tip called "Megs" sold for streetrods, simple chrome megaphone, various sizes.
Picture looks oval, but they are round

Nice look, not too expensive.

I was reading the thread and became curious. Pulled my paperwork of the exhaust install, about 10 years ago, and realized my memory is wrong. The piping is 2 inch however the flowmaster has a 2.5" inlet and outlet. I do remember telling them, "Put the maximum size pipe through the frame as possible". I got "It ain't gunna make no difference wit a 4 banger". Oh yes it did!

I got a new exhaust for Zippy. I gave them a flex coupler and gasket and they built the rest. They managed to get 2" pipe through the frame by making it a bit more oval in shape. The muffler is the smallest "turbo" muffler and they cut down a huge tailpipe tip to resemble the stock megaphone.
Sounds really good!
