Will Invidia Q300 muffler connect to TRD exhaust piping?
 

hey all

I've been looking for a way to quiet my car down even more. I've been looking at pics of the Q300 and the TRD exhaust, and it looks like the Q300 axle-back portion (muffler only) might line up with the TRD mid-pipe.

The smaller mid-pipe plus the larger muffler would probably yield the quietest results...if they line up. Can anyone confirm that the Q300 muffler would match up to the TRD mid-pipe?

Thanks!

No it will not. They have different connections at the muffler. You will need the midpipe and small S pipe to use it. It will line up, but finding a way to seal it properly will be your challenge.

Thanks! It sounds like you've seen both exhausts. Have you heard both exhausts? Can you tell me which is quieter in cabin under light load? or in any situation for that matter, which is the quieter of the two CBEs?

Thanks again

Q300 is the quietest system for this car hands down. I went with a Perrin resonated 2.5" to get a little volume back and UEL rumble in the cabin but 0 drone. That's the best part.

You won't hear much at all light cruising on the Q300.

Just my $0.02 as I have neither the Q300 or TRD, but much of the cabin drone is resonance or vibration that is passed through the trunk and into the cabin. The trunk has basically no sound dampening material and sounds very thin and tin-like when tapped on. I added 80mil sound deadening material to the entirety of my trunk area and it made a noticeable difference is exhaust cabin drone under acceleration. I still would like to do the rear seat area to increase its effectiveness, but as it stands it is a great sub $60 modification (less considering I still have enough mat to due the rear seats).

I am currently on a UEL with Zeta exhaust. The exhaust note is almost non-existent during cruising, but vibrates/resonates fairly deeply (at least to me) between 1000-2500RPM at acceleration.

k...wait, so you have heard both, right?

Now, you have a resonated Perrin because you wanted 0 drone. Does that mean the Q300 had drone?

Just looking for clarity, because the Internet.

No, the Q300 had absolutely 0 drone. I just could barely hear my exhaust unless I really stepped on it. Almost sounded stock inside driving normal because it was so quiet. The Q300 muffler is much larger than the Perrin, but the Perrin has a larger and longer resonator with a smaller muffler.

ok. So you haven't heard or driven with a TRD exhaust then. Correct?

People say the TRD is about the same as the Q300. I have a TRD, I think there's a slight "drone" with a slight load, or on engine braking. If they are about the same, then the Q300 will probably just be as loud, and I might as well not get one to save money.

The TRD does have drones at around 3k RPMs

The TRD is louder because the muffler is smaller. I can assure you the Q300 has no drone. I ran it with a catless header and catted front pipe and it was always quiet inside.

Correct. That's about where mine drones ever so slightly

But the q300 does not?

No, it does not, and hopefully other Q300 owners will chime in here and attest to it as well.

It's quiet as hell...... Sounds better than stock and better with Manual transmission. Don't worry cops ignore me when I'm driving around or near them. As for drone.....nope

Thanks folks. Looks like I might use $700 of my tax dollars. Some jerk dented my pass door though so I might have to pay for paint less dr instead. :(

What happen to your insurance, if you have one?

My deductible is $500. Pdr should cost less than that.

So to all the guys who have talked about the q300 - have any of you ridden or driven in a car with trd exhaust?

Even with a catless UEL header, you can't hear the exhaust inside the cabin? I have a Nameless 5" axleback and it sounds perfect right now with the stock header. I was thinking of switching to the Q300 when I purchase the Tomei header. I wouldn't want it any louder than my stock header+nameless, but I still want to be able to hear it while driving..

Nope, unless I went WOT, that's the only time you could tell I even had a header or a full exhaust. If I'm driving civil and regularly, it's almost as if I'm stock.

That's the reason I went with the Perrin 2.5" so I can at least hear my exhaust some, but not have the drone. It's the perfect setup I've found that balances quiet and loud right in the middle.

Damn.. sounds like it would be too quiet. Guess I'll just keep my nameless and hope it doesn't become too loud after the header. Those titanium tips are so nice though :(.

It will be too loud because those mufflers are small, but the stock midpipe has a decent resonator in it to keep it somewhat reasonable.

The Ti tips I had were faded when I got the exhaust and it progressively got worse. I ended up anodizing the tips myself with electricity and making them more of a blue color and they looked much better. Needless to say, I'm happy to be back to brushed stainless tips.

OP, did you end up getting the Q300?

I have the TRD exhaust and it's a little bit too loud for me. I'm thinking I might switch back to stock or try one of these Q300's. One of the most annoying things is the TRD exhaust on the freeway when I'm rolling in 6th and accelerate from 60-75mph, it is pretty loud. Likewise on deceleration that booming is pretty noticeable.

No. I'm stuck on the TRD still. I'm not sure if I want to sink more money into my car.
