Q300 too quiet! Help! - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Tjwells225 · 01-10-2017, 03:17 AM

So I bought a used Q300, looks great and sounds better than stock but it's TOO quiet! Is there anyway to cut out the front muffler on the system? I'm in CA and can't take off the Cat :/ trying to go the legal route, thanks in advance!

I mean, you could. But that would just lead to rasp. Sell it and buy something louder. That is the quietest system next to stock there is.

Try the Miltek or Perrin resonated. Or Tanabe single exit. if looking for rumble and just a little louder.

What kind of sound are you looking for? Tone wise and decible wise

Tjwells225 · 01-10-2017, 03:45 AM

Rumble and something that isn't extremely loud, just when I get on it and start up I'll be able to hear but won't wake the neighbors (every time) haha

How many miles are on it? Keep in mind it will continue to get louder and improve in overall sound as you log more miles on it.

Not sure how many the prev. owner logged (looks like a descent amount due to ware) but it has grown on me a bit and it looks great

I'm gonna stick to my previous options I gave. Non of which are super loud but have a rumble you can hear under throttle and cold start. With the rest of the exhaust system stock it will remain fairly quiet.

If you are dead set on keeping the Q300 instead of cutting it up you might just have an exhaust shop make a new midpipe so as to not ruin your current one in case it still isn't what you want and need to sell it. Would be harder to sell if it is messed with.

And since it is used I would imagine it is entirely broken in by now and not much change will come to it sound wise.

thanks for the advice and opinion man! I'll check out the Perrin options and see where that takes me Sound and cost-wise!

Shop around for a used one. You can usually grab one for under $600. Just make sure it is resonated to avoid rasp

You can also try putting in a High Flow Cat Front Pipe. It will make it sound a little deeper. That would be the cheapest and easiest route.

Q300 is not quiet dude...my greddy sp is quiet...

jasonojordan · 01-10-2017, 09:28 AM

Invidia N1 is loud but I would not recommend it if you ever plan to change from stock headers. With cat-less headers the N1 is deafening. I traded my N1 for a Q300 for once I do my headers here this spring.

Do you have the Supreme SP or the Elite SP axleback. I am actually thinking about getting the Supreme SP is it really very quiet?

Songha · 01-10-2017, 11:10 AM

I'm running full catless with the N1. I love it, it is really loud though. I wouldn't recommend it though, i thought just the N1 alone was loud ish.

JazzleSAURUS · 01-10-2017, 11:19 AM

I have a decatted stock header with an MXP SP catback. It sounds absolutely wonderful, very smooth, and reasonably deep. Very audible but still EDIT: WIFE approved. Pretty when you're hammering, but you can still hear the feedback from the rest of the car. I'm very pleased with the setup.
