Wo doing cats all muffs pass smog but if the tracks u go to have sound restrictions it's a pita to modify aftermarkets to pass sound. Also some muffler systems are way to loud ie pretty much straight pipe is way too loud for the street. Cargraphic sounds nice if they still make them. Mike

another happy speedtech exhaust owner here. i highly recommend... totally modular, you can go straight pipe muff delete or put the small muffs, very quick and easy. same concept for cats, delete or inline.
i have the small inline muffs and straight pipe in place of cats, works perfect, loud on the track but sounds a lot better and not as loud as bypass pipes (ie: fabspeed).
excellent quality, good price, awesome customer service. no affiliation, just a happy customer

I've been considering this exhaust, but not sure if it will pass sound. Any idea how loud this exhaust is at 50'?

muffler bypass (fabspeed) + stock cats. very loud and crappy sounding.
muff bypass + cat bypass (custom one piece unit) and it was CRAZY LOUD. open headers essentially. WAY too loud even for the track!!
my setup now speedtech system: small inline muffs + cat bypass, its loud, but not as loud as my previous setup's as mentioned above. sounds a lot nicer. might be a good idea to give the guys at speedtech a call and ask them if they have noise data. my guess... 100-105 db at 50' off wall.

Yes, we did some testing with the cats and in-line mufflers - we measured 89-91db @ 50' at 3500-4000rpm's. Also, the system has passed a 92 db track at full WOT without our optional track tips.
