This is what I did to my 69 Z, maybe an idea for you.
My car has some old school headers. So we ran 2.5 all the way to a flowmaster crossflow muffler. Then we ran 2.5 from the crossflow to the factory style tail pipes. The entire system was set up with the factory hangers. It looks very stock, but of course flows much better than one of the resto exhaust system and sounds awesome. For performance you would of course want to use 2.5 tailpipes. |

From experience, the DynoMax or Pypes crossflow muffler will perform better than the Flowmaster crossflow...on our Camaro that we race in Pure Stock [exhaust manifolds], we started with the factory chambered, went to 2.5" mandrel with Flowmaster crossflow & Dr. Gas x-pipe, then to the Pypes 2.5" mandrel with Pypes crossflow & Pypes x-pipe...picked up each time, and shockingly we picked up well over 1mph when we switched from Flowmaster-->Pypes. 2.5" mandrel head pipes are the key, and tail pipe size is last on the list...as long as the tail pipes are mandrel bent you should be fine with 2.25", as the gases have cooled significantly by that point and don't need quite the volume as up front...

I appreciate all the input I have received from everyone.
So far it looks like I can get the best deal on a Flowmaster kit with the Crossflow muffler - $550 Cdn. I can not find anyone who deals in Pypes here in Canada. I have sent them a message asking whether they have any dealers in the Great White North, but have not hear back yet. I am going to the Ontario Camaro Show this weekend and will look how some of these systems fit. There are so many choices and hopefully that will help me decide.

Over the past 10 years or so, I've become a big fan of http://www.torquetechexh.com/ They even sell a 3 1/2 inch system which wraps over the axle and really drarwf's the 3 inch systems that everybody seems to have these days. I've installed a few of these systems and let me tell you, if you got a decent rat motor up front, that 3 1/2 system really thunders!

I spent countless hours researching, buying and then modifying my ou7t of the box system.
I wanted the best fit, best appearing, best hanging, good performance, good sound, (I didnt care about absolute TOP performance) at a good price point. I found a MAGNAFLOW vendor on the net that had free shipping, NO sales tax. I had read many threads on Camaros.net and spoke with many people. My conclusion was the below system. ![]() ![]() ![]() ![]() ![]()
