I am trying to determine my exhaust setup. A four inch turbo back straight pipe may be a little too loud and will attract police on the streets. So I have been contemplating a muffler. I was thinking to do a four inch stainless pipe from the turbo back to the HKS Ti or HKS carbon Ti muffler. I like my cars loud, and I am hoping the HKS muffler will still be loud enough for me. Obviously, a four inch turbo back open exhaust would be loudest, but looking for a muffler to tame it down a bit.

Does anybody have any video clips or examples of a four inch turbo back to an HKS Ti or Carbon TI muffler? I am looking for loud cold start and overall loud when WOT.

Any feedback is great, thank you!

I went from stock to HKS carbon to HKS Ti to 4” straight pipe to open downpipe on my race car.

Stock - 1
Carbon Ti - 5
Race Ti - 8
Straight pipe - 10
Open downpipe - retarded

My car has a 4 inch downpipe and midpipe to a full hks carbon ti exhaust. Coming from a boostlogic 4 inch it’s the perfect amount of sound to me.

Sounds great, but a little more quiet than I’d like, prefer louder than this but not much....^^^^^^

I've got a 4" into a boostlogic series I muffler.
Loud AF and deep/bassy. I love it.

Sadly I don't think boostlogic offers the series I & II mufflers anymore

This is a clip from the previous owner of my car right before I bought it, was fully BPU at the time, I'll be using the same exhaust on the car now that it's fully built + APU, I have a few more vids of it at that point in time just let me know if you need them!

Exhaust in vid is HKS Ti (4 inch....but technically not 4 inch if you actually measure it)

mkivsoopratt,

The straight six sound of an APU Supra CANNOT be beaten! The car sounds fantastic, man.

Here's my HKS Ti. Cold start when my car was BPU



I am just wrapping up a single conversion + GSC S1 cams. Sounds soooo much nastier now. I'll get a sound clip of that as soon as I can and update .

Wish there was a way to get a replacement boost logic muffler. Not looking forward to the day mine blows out the packing material from anti-lag/2step abuse.
Love the way it sounds, no other system I've seen has the same super deep tone & rumble.

This is BPU? Sounds cammy for being BPU.
Yeah that's the car as I bought it back in 2016, GSC s1 cams untuned, BPU with a lot of pluses. Completely different car now though.

Wow, these cars all sound great.

mkivsoopra, do you have any driving vids or hard acceleration? Trying to gauge sound levels. Thank you!
