After market exhaust in MA

[Ldub]

Scott,
How much improvement did you notice w/ aftermarket exhaust & what did you use? I'm supercharged (well,actually my VX is) running original exhaust.
I noticed an appreciable gain on the butt dyno. after installing c/f intake & cone filter, but I'm having trouble deciding which muffler/exhaust to go with.
Yeah, more power is good, but I don't like drawing undue attention with a loud exhaust note.
Thx,Ldub

There are several United States Acts are already in place that allow aftermarket exhausts and other modifications (Like the SC is CARB approved with the stock airbox in place). A muffler change can NOT be reason to fail an inspection and certainly not an emissions test since it does NOT affect emissions in any way. Too loud, on other hand, is subject to control by local agencies.

Scott,
This sounds like it might become a "pissing contest" between you and the DMV in Mass.
I have never heard of a state not passing(other than noise restrictions) a vehicle because it had a modified exhaust system. As long as the VX passes emission standards there should be no questions.
(Otherwise buy an acre in Vermont where we don't have those problems..JK)

I would make a phone call to the Commissioner of Motor Vehicles and get the real scoop on what's going to happen now before it gets nasty.

Hey Scott,
Are you using the stock air box like Tone says? And if so did you happen to keep the oem? If you didn't and need one to use for the Inspection let me know I still got mine here. I can just feel it coming to RI. I had a 300ZX turbo that I had moded and the cops tried to give me a ticket for it. I fought the ticket went to court armed with video of Harley that run straight pipes. When I showed the video to the judge and explain that even police officers that had harleys with straight pipes it was thrown out. I didn't even have to pay court cost. I beleive that RI is trying to change the loud exhaust laws but since alot of RI have harleys I can't see that happen anytime soon.

I do recall reading a few months ago about MA putting this law into affect. It is specifically for noise ordinance, but to make it fair to all exhausts, they had to pass it on ANY aftermarket exhaust. That really blows. I dont think that council really thought that one over very well. I dont know how this can be beat without a torch and pitchfork rally.

Seems like we could get some place like a trophy shop to stencil the isuzu logo on it and they would have a tough time showing that it wasn't an OEM part.

Great ideas but I can't register it out of state, etc. Tony, I have the OEM air box and thanks but I'm running a K&N intake (By the way, my boy remembers you!). The "muffler" is the original PV (not version 2). I watched the inspection and noticed that one of the guys literally went underneath the car to affirm that the muffler was not stock. Oh, on another note, I was under the impression that the OEM exhaust with an SC was contraindicated...Tone? Anyway, MA has been making noise about this issue since last year. I had been turned away from one inspection station when they realized I had an after market muffler stating that they would need to call the Registry of Motor Vehicles to perform a sound test on the exhaust or, I they could just forget I was there and take my VX to someplace else. No lie. Things are getting a little crazy here and it's not like the PV is making THAT much noise. Sheesh.
