Ebay score. NOS Dynomax 17266 Ultra Flo 304 SS mirror polished muffler $99.00 Free shipping or Make Offer. $85.00 offered and accepted.
Been discontinued for about a decade and was about $200.00 back then. Not bought for any reason except for get it while you can. Might be a future upgrade for my friends TTA #3 "The Driver". A straight-through design muffler is what you want on a turbocharged car not a baffled style muffler.
The claim of 2,000 SCFM and 1,900 HP is ad copy that DynoMax puts on all mufflers of this design. As a OEM Direct-fit muffler with a 2.5" inlet and dual 2.5" outlets one would have to live in Wonderland to believe that but it flows more than enough for whatever we will use it for.
DynoMax(R) Ultra Flo(TM) SS Polished performance mufflers are constructed of stainless steel for lifelong durability and completely polished for show-quality shine. The unrestricted, straight-through design is dyno proven to flow up to 2,000 SCFM and support up to 1,900 horsepower. Each muffler uses our exclusive Continuous Roving Fiberglass (CRF) Technology to absorb unwanted interior resonance while maintaining a deep performance tone. The 'Pure Unadulterated POWER' of DynoMax(R) Ultra Flo(TM) SS Polished mufflers are backed by a Limited Lifetime Warranty and exclusive 90-Day Performance & Sound Guarantee(TM).

No it's not going on the 18k mile 1987 5.7L CC1 T-top IROC-Z in the background. I thought the IROC-Z would be a nice backdrop for the picture. What's in the RockAuto box under the Dynomax muffler is going on it.
