Making TRD exhaust louder
 

Hello everyone just got my Frs recently, after owning an IS300 for several years, and I absolutely love it despite the occasional torque dip and lack in power. However, the first thing I wanna replace is the exhaust. The stock exhaust sounds ok but it's really lacking tone and resonance. I've watched a ton of videos and the sound I love the most is the TRD exhaust. It has a very smooth, mature sound but it's a little bit on the quiet side.


Any tips on how I can make it a little louder without ruining the tone of the TRD exhaut? Any tips/suggestions are welcome, thanks for your time!

1. UEL Header (catless if u want to kill the torque dip) + Tune for more power and to get rid of the CEL from a catless header
2. Larger diameter Front Pipe (FP) upgrade to 2.75" or 3.0"
3. Larger diameter Overpipe (OP) upgrade to 2.75" or 3.0"

For bonus points go catless front pipe. Warning though, you will smell exhaust in the cabin at idle which can't be healthy.

CNT UEL Header --> Ultimate Racing 2.75" OP --> Ultimate Racing 2.75" FP --> TRD Catback.

If you don't want to do the rest of the exhaust, you could get a shop to cut the resonator out.

Thanks guys for the wonderful input! I decided I'm not gonna go with TRD but instead go with Invidia N1 + Berk Front pipe. For the price of TRD I can get two things improved and be happier with it. :thanks:

you could drill holes in the muffler :thumbup:

Haha good point

I did that to my 88 Buick Century when I was 16. Protip: it sounds like an exhaust leak, because you gave yourself an exhaust leak.
