TRD Exhaust Reviews?

[Darryljr11]

Adding a front pipe to the exhaust (especially a non-catted one) should add power.

According to TRD USA(1-800-688-5912), their cat-back exhaust uses the same stock diameter tubing and if there is any hp/tq gains they don't know. For an MSRP of $1100, i will have to pass.

Well if that's true that does kind of suck... I thought it would at least be 2.5" but I'll still measure it to confirm. Sad news if true, I like the look and sound but I don't think anything below 2.5" is worth the $950 I paid.

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.

Yes, welcome to the forum.
I agree with what wbradley has to say. I also have the Magnaflow, and like it. It has a nice deep tone without being loud. I'll add that it has a nice subtle burble and grrrrr when you get off the gas, or pull a downshift. I'm about an hour away from you in Prince Edward County. If you want to hear it for yourself, let me know.

Axlebacks and catbacks don't make hardly any HP/TQ. The header, OP, and Front pipe are super restrictive. Simply just running the stock catback with an OP front pipe replacement yields pretty significant gains.

I don't know if Visconti was referring to just axlebacks/catbacks or headerbacks, but full exhaust systems have proven to increase performance for many years across several cars. The FR-S/BRZ is no different.

If that were the case, everyone would be running stock exhausts at the track and road courses, wouldn't they? I'm no engineer, but it doesn't take a rocket scientist to figure out better flow, bigger piping, and non restrictive bends yields power gains when an engine can breathe better.

Not necessarily. You have to consider the exhaust may be optimized for this
2.0L engine and that unless you make significant changes to the amount of air going into the engine (ie turbo, supercharger, or very well designed intake with cams etc) there is only so much gas the exhaust has to get rid of.

I went out and measured my TRD exhaust today (O.D.)... So the axel back portion is 2.5" (8in circumference) but the mid pipe seemed to be smaller. I measure the diameter with measuring tape so not extremely accurate but when I held it up it appeared to be 2.5" but the circumference is only ~7in so hard to understand that math. I have read that changing the mid pipe doesn't translate to gains at least stock but I'm sure with forced induction you may want larger diameter.

Remember you don't need to have the system shipped, saves you $

If you are leaving the rest of the exhaust (headers, over, front, cats) stock, sound and looks are definitely priority over "performance gains", which are honestly so small you won't feel them.

Has anyone here done this? I'm curious to see how that turned out.

I'm curious as well. Can you buy the TRD tips by themselves? If I could, I'd buy those or just the muffler portion.

Still no dyno for the TRD exhaust?
