Greddy 3 inch silencer.

Maciej · 09-16-2019, 03:15 PM

I just got a 3 inch Greddy single exit and test pipes. I am probably going to be putting a silencer on it.

Does anyone know if these would be the right ones?

Also would the 51mm or the 43mm silencer be quieter?

Why did you get a single exit if you're gonna put a silencer on it? Doesn't that defeat the purpose?

wait.....people want quiet exhausts?

When I drive it during the day no silencer. But when I leave for school at 5am I think my neighbors would really appreciate the silencer...

JARblue · 09-16-2019, 08:32 PM

Oh I didn't realize they were removable. That's convenient. And courteous of you

It looks like the measurement is diameter. I think the smaller diameter will provide more noise restriction?

Yeah that’s what I was thinking but I’m not sure, I’ll prob give Z1 or Greddy a call. Also I love how I got roasted at first lmao.

More of a side effect. Single exit is half the weight, and often, price.

Unless you were being facetious. Then I'll nerd my way out.

^^ this. One of the reasons I swapped non-res F.I. for 18" is bc the loudness meant I couldn't leave my garage after 8pm, lest the neighbors burn it down while I was out..

I understand all this loudness stuff, same with my apt, the garage I have is under a apt unit (not mine), so always concern.

The 43mm is quieter then the 51mm. Also a cut in power too.

Rusty · 09-17-2019, 11:27 PM

I feel sorry for you guys that have to watch the noise levels in your hood.

Should hear my hood in the spring on weekends. Everyone is bringing out the race cars and tuning them for the coming season.

FPenvy · 09-18-2019, 08:52 AM

you people disappoint me

i ran straight pipes for 3-4 years and no issues with neighbors. even now with the mufflers on currently it's still way above anything else still no issues.
