Can anyone here please tell me, with absolute certainty, WHICH flowmaster 44s fit on this vehicle? (part number would be nice but diameter/ offset/straight etc will work) ...
Thanks.




If you've done this, I'd appreciate your input. Also, any 'other' modifications necessary, i.e. welding, extensions, etc, or is this a 'direct replacement DIY project' ?

Thanks again.

Offset/Offset, 2.5" inlet/outlet, 18" can/22" OAL (may still need a bit of pipe at one end - it's hard to exactly duplicate the stock muffler length) and yer good to go.

Unless they went bigger on the Gen2's... mine was 2.25" offset. I am running Delta Flow 40's.

I guess they switched from 2011 to 2012, because I used 2.25" Magnaflows on mine...even for the resonator delete from Blastin' Bob's they list the size as 2.25" for years 2011-14, and I bought and installed this as well...

0.25" difference ain't no big deal to fit up. Either a pie-cut on the pipe, a small machine expansion bell to expand one end or a short 2.25" to 2.5" adapter will all work. And a 0.25" difference either way won't make ANY performance difference for a stock 5.7L engine.

Either way it IS easy enough to fit. I was only stating what I personally installed and it was not too difficult as a DIY job.
