muffler case size

dgc333 said

I have Flowmaster 50 Series Delta Flows under my Cuda. They are 4" thick, 9.5" wide and 17" long. I have 2.5" offset in and 2.5" center out. These are resonably quite at cruise with no resonance but have a nice bark at WOT.

Don't get hung up on individual muffler flow numbers. All performance mufflers flow more than the engine produces. Make your choice on sound.

yea my buddy has the 50's on a 572 Nova and they sound wicked...that case is also pretty similar, if but a bit smaller than what i was planning on going with...im not really hung up on flow numbers..imo straight through mufflers sound much much better than any chambered muffler, and the Borla's sound wicked! its just a bonus that the flow good and are wicked loud! (115db at idle...yea baby!)
