I am going to get the Series 50 flowmaster mufflers for my small block 69 RS/SS. I need to know from those of you that have dual exhaust with two mufflers, do you have mufflers that have center in/out or center in/offset out or offset in/center out. I am not sure what would work out the best by just looking.

I have a 69 SS with a 454 in it and flowmaster 40s. They are offset in and center out.

Be sure to check the length of the 50's for proper fit if you plan on installing them in the stock location.

I have the Flowmaster American Thunder Single Muffler system on my 69 RS/SS . The muffler tucks up in the stock place and sounds great.I had the muffler shop put the good chrome tips on it that give it a stock look. If you went with the dual muffler system you lose a lot ground clearance the way the stock floorpan is on a 69 Camaro.Thanks Rich T.

You got the answer, off set in, center out. I might add; The Flowmaster Delta 50's will fit but they require a bit more talent to install. (As I'm told.) As the story went, the input and output pipes need to be trimmed back a little. I'm not quite sure on this. I'm checking another shop before this happens. (This will be the third system in as many years.) Bottom line, be careful when deciding on the shop you'll use or go slow and sure if you do it yourself.

Currently I have a dual Flowmaster Delta 40's and the interior resonance is just too much. I just purchased the Flowmaster Delta 50's and I'm waiting for a Dr. Gas "X-Pipe" and the rear tailpipes. The Delta 50's need to be cut, trimmed and snugged in. I hope this will be the "tune" I'm looking for.
