I totally agree with you. The Performance Muffler is actually a rather quiet unit, as far as I'm concerned - and, I think it probably would pass a California Inspection. It's just not CARB approved. I gave the response to ObeyMyFast! because I didn't want to mislead him to the effect that it might be "Street Legal" - which is still the case, as it is not approved. I'll bet it will pass an inspection though.I hear ya Ralphie, but I have one on my car and do not believe the limitations listed in the product description are totally accurate.According to the Ford Racing Parts Catalog, NO!
I had my delivering dealer install the unit before I drove it off the lot. And if there was any limitation on emissions contamination, the dealer most certainly would not have assumed that liability. I can see no physical reason for the emissions statement.
Yes, the Ford Racing muffler M5230-GT (manufactured by Borla) is slightly louder than the OE muffler but only noticable under hard acceleration. Otherwise it is quite mellow with no driving harmonics. It is certainly more quiet than all other exhaust/muffler options guys are using on their GT's and I was in attendance for the "muffler-off" sound comparison at Rally I and heard them all first hand. The Borla was closest to the OE muffler and only slightly louder.
I would not hesatate in the least to put this muffler on a street driven GT.
Correct - and I don't know of any Inspection Stations that perform a decibel test either - just an emissions test.How would inspection station personnel know it wasn't the factory muffler in the 1st place? 'Can't see how they'd have a clue.
