Hi all...tried to search, but apparently “HKS” is too short? Does anybody who has bought the HKS dual tip exhaust for the MK3 (75mm) know what the lengths of the muffler and the resonator are? And is the muffler a “direct” type like the Dynomax UltraFlo’s? I want to construct a similar custom exhaust, but I wanted to get an idea of what the specs are. Thanks!

I don't have any problem with mine being short, if your cat is short it will pull the whole cat back forward. I can measure the muffler and resonator next time I'm out there. the muffler isn't straight though it's a baffled system I believe which is why it's so quite.

What exhaust is on your car now? If its stock cant u just use that as a guide, increase the diameter and insert your muffler of choice to construct your own? My car originally came with the hks sport and it fit like stock. If the lenght is the issue run a test pipe and adjust the lenght accordingly. I had a machine shop take a few inches out of my test pipe with my random tech. down pipe and blitz nur spec exhaust.

Thanks for the input. If anyone wanted to take measurements I would appreciate it.

Haha...I think there was a misunderstanding. I was saying that the phrase “HKS” was too short for the search.

HKS 75mm turbo exhaust. It is a straight through, and about as good as you can get performance wise. It is also quiet. The other part is the resonator, since the muffler is straight through, and not baffled like Supra internet lore.

This is my inspection camera being pulled out of the inside of the HKS LET-T16 muffler starting at the input bend (see Nick's post above) through the muffler and out the tips.

This confirms it is a straight through design.

Thank you! This is great. So it's definitely a straight-through. Is the muffler about the same length as the stock one?

I know it is a couple of months ago now....I have a digital photo somewhere of the straight path through. Video works too.

I have the HKS Super Dragger II. I love how the exhaust sounds and how quiet it is. BUT I hate the size of the can.

This is a great looking exhaust and so is the Tanabe Hyper Medallion

Probably too late, but I measured the muffler tonight.

The length of the HKS muffler itself was 17 3/4 inches, and about 25 1/4 inches to the end of the longest point on the tips.

The stock muffler was 21 inches and about 26 3/4 to the end of the longest point of the tips.

It is rather curious that even though the HKS is shorter its tips are longer so they stick out from the car a bit more.

Here is a pic I took, sorry they are not perfectly aligned:
