Non-res down pipes in Mass

[ARoach04]

Hey Guys,
I'm planning to add non-res down pipes to my AWE system, has anyone ever had any issues with emissions here in Mass after installing them?

[Acejam]

Emissions won't be an issue since MA is purely ODB-2 based. However, sound will be. State Troopers are extremely strict on sound levels since the law basically reads "anything louder than stock is illegal". Some local cops don't care, but some do.

Ok,
Thanks for the confirmation and warning. I'm still running the Touring version, not the Track version, so it should be too loud.

I've been running catless systems in MA for over 6 years, between my B7 S4 & B7RS4, aslong as youre running software that delete any CEL's you'll be fine.

[ARoach04]

Ok. They are being delivers tomorrow. I think I can delete CEL's via Carista, but if they become problematic I'll prob go back to stock

I thought if u alter ur ecu not not give iff a cel for rear o2 you automatically fail?

I run o2 sensor spacers instead of altering my ecu. Works perfect on last 3 cars

Emissions shouldn't be an issue since you will still have the cats on the car still

If you run software that does not run monitors, you may get kicked to a MAC center for the state. If you do that they will go through your whole and make you put everything on the car back to stock. It is something you do not want to experience. If you run spacers the car should set readiness and no faults. You may have to try different spacers with angles and varying lengths, but it should work. My recommendation is to run spacers and verify that all your readiness codes have passed before getting a sticker. I check all my modified customers cars for readiness codes before a sticker is performed.

Thats what i thought and why i never bothered lol i have my egts disables but not rear o2s on my b5 s4

[ARoach04]

Now you guys are starting to scare me. If I already have an AWE exhaust on my B8.5 S4, and am just replacing the downpipes, am I going to have issues?

+1

non res downpipes on the B8/b8.5 S4's still retain the cats
OP, not sure if you're implying issues with a visual inspection - not familiar with MA laws

[Davido1]

It will pass inspection

[Acejam]

If you get a friendly shop, it will pass inspection. However, if you get a strict shop, it will easily fail inspection because it's significantly louder than stock.

OBD-2 will pass anywhere because you still have cats even with non-res downpipes, but a visual/subjective inspection will fail, because it's loud. (MA law basically states cannot be louder than OEM)

Ok,
I def. have a friendly shop (my dealer), so that won't be an issue.

Sounds like your good to go! Will you be at Cars and Coffee Saturday? (I think we've met before, I had the Black 2014 Black Optics S4)

The Audi dealer does inspections or will get your car inspected for you? I only ask because Audi Brookline does not inspect cars, but will take your car across the street to a local inspection station; it is out of Audi's hands in that scenario.

I ran into this problem moving here from SCal. I had APR Stage 2+ w/034 HFC and got flagged to MAC. Had to remove HFC and retune. Now I'm trying to figure out how to get my HFC back on because I can definitely notice the loss in torque. Any suggestions?

Throw the hfc back in. Then get some 02 sesnsor spacers. DONE

Understood. This is well known in MA and has been around for quite some time.

No person shall operate a motor vehicle, nor shall any owner of such vehicle permit it to be operated upon any way, except fire department and fire patrol apparatus, unless such motor vehicle is equipped with a muffler to prevent excessive or unnecessary noise, which muffler is in good working order and in constant operation, and complies with such minimum standards for construction and performance as the registrar may prescribe. No person shall use a muffler cut-out or by-pass. No person shall operate a motor vehicle on any way which motor vehicle is equipped (1) with a muffler from which the baffle plates, screens or other original internal parts have been removed and not replaced; or (2) with an exhaust system which has been modified in a manner which will amplify or increase the noise emitted by the exhaust.

I have never had an issue with this and have had exhaust systems on every car I have owned. I got yelled at for straight pipes on my corvette (which was excessive) but no tickets of any kind. You will be fine with an aftermarket system.
