which is the most Quiet aftermarket Catback?
I installed the exotic speed on my 8 with the midpipe and the RB header.
The sound was really great but i want to make my car more silence in case i am traveling on the high way A lot of hours Listen to the sound that i have now here: http://www.youtube.com/watch?v=6oTGgL6yNqA http://www.youtube.com/watch?v=mqC5DiI1rfQ So which is the most quit cat back? |
what are you trying to accomplish with the aftermarket catback? you're pretty much just getting sound so if you want to deaden the sound, are you just looking for different tips?
|
I've heard the Racing Beat Catback is pretty quite.
|
i want the more power i can get and a little bit more deep and wankel Sound But not like 120+ db tha my car should sounds now

You have headers...hi-flow cat...and exotic speed exhaust and are surprised that it is loud?
If you want quiet...stay stock. You won't get very a lot of hp from exhaust mods...I've done (and will do in the future) these mods for listening pleasure. I'm guessing it is the exotic speed exhaust that is really giving you the loudness. I noticed a measurable difference with my addition of a hi-flow cat to the stock exhaust system. It is a bit deeper and the engine feels much less restricted than before. The person I bought the hi-flow from said he had it mated with a Magna-flow and it was "way too loud". I dunno...I never heard his set-up. You should try the stock cat-back with the headers and hi-flow cat. Probably the best way to cut out the loudness and retain as much of the benefit? I dunno...exhaust is obviously not my forte. Good luck |
Hmmm. I run a racing beat catback cut at the flange for a slip fit with a RP Supercat and a resonator. My car idles more or less silent and is only noticeably louder than stock at WOT. Even then, it's much quieter than most modded 8s (even though my cat is gutted). The key? I'm also turboed. Therefore, you should put a turbine in your exhaust to get rid of all that excess noise.
Seriously, though, even on the dyno my car is almost always the most quiet there. |
I know racing beat is pretty quiet compared to other catbacks for the 8 and i believe that the mazdaspeed catbacks are pretty quiet too. Like mentioned above if you are headers and a midpipe the exhaust is going to be loud

The Mazdaspeed catback is pretty quiet.
ExoticSpeed is one of the loudest ones I've heard FYI.. |

The Mazdaspeed single/dual canister has one of the lowest decibel cat-backs. Single being the lowest then the dual cat back. Than racing beat and borla would be next on the list. I installed a Borla and Exotic Speed High Flow catback the other day and I had to take it up to 7-8k to even get anything louder out of the exhaust. The Borla I think is one of my new favorites. |
You could always have a resonator or something welded into the exhaust to take some sound out.

I've compared the RB next to the MS catback side by side and the RB was quieter.... heres my RB with a Midpipe: [embed]<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/m38RiYq3FdA&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/m38RiYq3FdA&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>[/embed] |

but only by a couple pounds... a difference 99.99% of us will never feel on our street cars..

That could have been the difference the one I was referencing was using the Exotic High Flow Cat.

And the legamax? is louder than the REv8? |

When comparing car parts it is alway a good habit to talk about a broader spectrum of features. If i recall it right RB's weighs more than the stock one. |
I havent heard the Tananbe in person so i cant comment... but from what i read and personal experience... the RB will be the quietest around
