Temporary Ways to reduce exhaust noise? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I live in an apartment building with an underground garage, after I installed my invidia N1, everytime I start my car someone's car alarm goes off. 50% of the times I get home someone's car alarm goes off when I'm parking. and this is with the silencers installed.

FYI about the silencers: [ame="http://www.youtube.com/watch?v=Xh3J8r-IgpM"]http://www.youtube.com/watch?v=Xh3J8r-IgpM[/ame]

Just like the guy in the video, the car makes a lot more noise during cold starts. Nonetheless, the car still starts up car alarms when I get home.

The silencers do their job but it isn't enough. I'm asking on ways to reduce noise while the car is in the garage, and then I could remove it exiting the parking lot.

While the engine noise is great, and I love my exhaust, nothing really prepared me for this sort of problem (most reviews say it's loud, I just didn´t expect it to be this much)

I don't want the homeowners association to start troubling me about my car noise, particularly when I get home late or wake up extra early.

Well, @OnionTou ..... you might consider buying a inexpensive glass packed muffler (about $25) and cut it half, then slip the outlet/inlet sides over your tail pipes while your car is in the garage......

Move out of the apartment or park in the streets. Joking aside, I don't think there are any temporary ways to reduce noise from the N1 except for silencers.

This isn't a silly idea. My fabricator uses a similar thing he fabbed up. It's basically just a muffler he slips on the tip of a car he's moving, that would otherwise be super loud.

Actually, if it weren't for the silencers (and the sound deadener I put in with my car audio), I wouldn't be able to listen to my music inside the car.

The silencers come off on trackdays, but on a drive around town, they make the car more useful.

with the silencers, the car is not that bad, its just the way my carpark is built, very closed in, so the rumble of the car, just doesn't dissipate.

the car out on the open, standing around the car, it doesn't feel so loud under 3k, but it does make a bit of a racket inside.

If you install the silencers, it helps keep it down inside, and I can enjoy my music (after having spent some money on that, Its a shame not to enjoy that).

Could you get him to give a bit more details on this? It sounds like the perfect solution for me, and maybe a few others who might have a similar issue.

Theres an oft tune that reduces startup noise i have the n1 also and and it reduces startup noise and it revs lower when you start it!!

I rev mine a bit & this seems to bypass the loud warm up. 1 sec of loud better than 20-30 secs. Not sure if good to do all the time though.

same, but it doesn't solve the fact that the neighbor's car alarm still goes off.
