TRD Exhaust Reviews?

[Spicer66]

Just curious, anyone know what happens to the stock exhaust bits when the dealer installs the trd? I forgot to ask.

They probably toss them unless you request to keep it most likely. Just look on the classified section, no one wants the stock system.

They told me, they will give it to me when they will deliver the car.

for all the popular exhaust systems mentioned, are they all bolt ons? Or do they require any welding and cutting involved?

I assume so; it's the easiest swap I've ever done. I put on a Borla the last time I changed oil, and I had the job done before the oil was completely drained.

I picked up the Magnaflow. Straight bolt on, and the easiest cat back I've ever done. The stock system came out in one piece within 5 minutes of putting the car on stands. Nice.

I personally really like the D tips so that's just preference but the sound is great as well! It has just enough tone to notice but not get annoying. If you are planning for FI this may not be the exhaust for you, though I still plan to get a supercharger that is more on the modest side (even if I have to redo the exhaust). It also provides peace of mind that I can call up my dealership if there is a problem and they will take care of it also the quality is unquestioned. Yes the price is steep but I'm the type of person that will buy what I want no matter the cost so save $200 now regret it later or not, many of the other brands are very good as well (at least from what I hear). My point is don't listen to people that hate it for various personal reasons and just get what you like and trust because you'll be the one that has to look and listen to it for as long as you have the car.

The TRD has little to no gain... Lots of exhausts add a good amount of power. Perrins had their resonated and non resonated dyno'd and did the best out of all the ones on the market. It was around 10 whp and if you get a header back you can expect more.

TRD's I remmeber reading that the exhaust is just for sound like the STI exhaust and was dyno'd and had no gains at all. 10 WHP is a big difference whether you like it or not. Why even get an exhaust that costs 1k if your not getting anything besides a change of sound. You might as well just get a Megan Exhaust if you care about sound/looks. Or just change your tips.

I think you'r wrong because i never see any dyno with the TRD exhaust yet.

And if you look the shape compare to the Perrin, it's pretty similar and surelly remove some back pressure and increase a little bit the flow. The TRD is more direct to the rear muffler.

I do not see why the TRD exhaust can't produce more HP. I plane to doing a dyno run when i will get it. We will see.

The size of the piping isn't even known on the TRD. It could be 2.1" just like the stock system. It is highly overpriced, and for what is offered aftermarket out there... much better alternative options for price/performance.

[Jacob G.]

I'm putting on my Motiv front pipe with HFC this weekend so I'll measure the diameter when I get under there... The design of the TRD exhaust is very similar to Perrin so unless the diameter is different I don't understand why I wouldn't get similar performance. The Perrin exhaust doesn't save enough weight compared to TRD to make up the difference in performance. Yes the TRD does cost a lot for cat back exhaust but for me it's been worth it. I don't care what people choose, I just wanted to give my opinion so people can make their own decision while people are constantly trying to convince others that their thought process is the best. I'm not a perfessional racer so saving every little bit of weight wasn't my concern, just design and looks. Besides unless everything else on your car is maximized for weight loss you have a lot left to do..

So guys what IYO is the closest sounding aftermarket to the trd d exhaust? Cat back only.
Don't want it too loud at all but growl when you pound on her.
New here also, hello everyone, thanks for having me.

Welcome to the forum and the FR-S!

Your question relies on the subjective opinion of someone who has heard the TRD and others that sound similar.

I have the Magnaflow which you can buy from JRP here in Canada. It has a nice deep sound at low RPMs like the factory should have sounded and the deep part tapers off above ~3000 revs so there's no drone. The tips are double walled and look top quality.

I read on the forums and a customer that got the TRD exhaust that their was little to no gain when he had the shop who installed it dyno the exhaust. Its been said around these forums already and I am sure a lot of members wouldnt be commenting the same thing that the exhaust is just for sound/looks if that werent true. Its been said a bunch of times since it released.

Dont you think TRD would of posted what it would gain if it did get anything. The STI cat back/TRD exhaust are both just for looks/sound.

Funny .... I've been reading in the ECU section where Visconti opined that catback systems add little to no HP gains based on his dynos. Not sure what he said about the headerback systems.
