Not for the resto crowd, but any FAST racers running either of these Mopars may be interested....... Firstly, a reply to an email I sent: WOW Mal - I wrote that a long time ago - I'm surprised you recalled this. The systems on the AAR's & T/A's were dual 2.25" - I own an AAR, though it is not ready for the road yet - still under a tedious restoration. The OE mufflers (reverse flows) are just a poor internal design so they flow like crap. We flow tested one of them when I worked for Dynomax, that's where I got the 156 CFM flow #'s from. Compared to a Dynomax # 17675, which has a flow rate of 517 sCFM. I would not hesitate to run this Super Turbo on your car, as it has a VERY good flow rate. The 2.5" version of this same reverse-flow muffler is part # 17676 (the 17675 is a 2.25" in/out) & the 2.5" version has a flow rate of 539 sCFM. These are a standard oval size (4.25" thick x 9.75" wide), x 14" long bodies, so they are shorter than the OE AAR/T/A mufflers by 6". Eric Sauls President � CCEI Classic Chambered Exhaust, Inc. P.O.

Don't recall any flow numbers. Does this ring any bells? Often thought of asking whoever makes the T/A exhaust system to make 3" available and without the deflectors in the tips...........

MB 2 aspects caused them to rust out easy... the gases plow into the wall and if you run short times it never dries up the moisture... once the aluminized coating burns off it rusts easy
