Yesterday I took the ’99 SHO into the local performance exhaust shop called FMS Performance. I asked the owner, Mike if he could sell me Dynomax Ultraflow mufflers like I had on my ’73 440 Charger Rallye. He said, he’d have to order them, then asked me why I wanted THOSE particular mufflers (this was back in 1997 when I bought them) since their construction was sub-par and straight through design was similar to the much better constructed Magnaflow mufflers (he had a cut out model on display). I agreed that muffler design/construction had come a long way since 1997 and deferred to his experience (considerable) to swap out the stock mufflers and weld in Magnaflow 11235s reattaching the stock tips. Well, when I came back to pick up the car, I couldn’t tell that it had been worked on. The tip positions looked EXACTLY stock. He said: “You’ll like ‘em now!” Yumpin’ Yimminie! He was right! The Magnaflows make it seem like puberty hit the SHO and it went from wheezing Tenor to a nice strong Baritone at full throttle. Now that the car can actually EXHALE, it scoots better too! He said he could give me a little more by going 2.5” pipe all the way back from the third cat. I insisted that I had to be able to pass visual CA nazi smog inspection, and he said that would do it. WOW! I can’t believe it is the same car! All I did was swap out the stock mufflers and it’s like I fell in love all over again! I’m thinking for the extra $200 to do the rest of the piping would be money well spent. The muffler swap cost me $300. Mike is SO experienced; he has a waiting list 2 weeks long to get on his rack. Guess I’m gonna have to go back to the end of the line and wait my turn again.
