I wanted to know if anybody has a video or ever seen one that you can hear a straight pipe gt-four? (De-cated oem) Stock or aftermarket exhaust, it doesn't matter it's just to give me an idea. I can't seem to find a video..
I could go this way though Idk how it would sound and I don't want it to be too loud.

Please describe how one would have a stock straight pipe exhaust.

straight pipe refers to the straight pipe put in place of a cat convertor unit on a regular NA celica, or other cars. on a GT4 the cat convertor is part of the downpipe off the turbo. Btw I thought you already had a 3" downpipe?

Anyways the question you're really asking is how different does it sound having a 3" downpipe as opposed to the standard downpipe and I can tell you this,

Stock downpipe with cat smashed out = not so much difference

Going from stock downpipe to 3" aftermarket downpipe (complimented with a full 3" exhaust system) the difference is great, the engine is more throaty, and you hear alot more engine sounds, you also hear the difference between wastegate open&closed.

No cell phone can really do the 3s-gte justice, but here is the best run i recorded back when i had a relatively stock 3sgte with just intake and 3" downpipe and full 3" exhaust, this was with 2 oem style oval mufflers so very quiet for a 3sgte (comparatively, but yeah alot louder than what it was with stock downpipe)

This is what it sounded like after custom manifold, garrett turbo, full 3" exhaust and one of those oval mufflers replaced for a resonator

Straight pipe exhaust actually refers to having no cat, no resonator, no muffler. The equivalent of running open header(s) or downpipe with just a pipe extending it to the rear of the car.

Just google straight pipe exhaust and you'll see this is correct.

My st205 has a 3" DP (Berk), 3" mid-pipe with 100 cell magnaflow cat, and 3" kakimoto exhaust (exhaust tip is around 700mm I think...very big).

I don't have sound clips but I can tell you that it's loud as hell.

I set off this one guy's car alarm in my parking garage every time I start it up. Not revving it, just cold idle.

I also have a tendency to set off car alarms of people parked on the side of the street if I give it more than about 50% throttle.

Exhaust pops quite nicely when off and then back on throttle.

Very throaty sound. I like it, but it gets a bit old after a while when you just want to go from A to B.

The difference in (apparent) power is definitely there. The turbo spools so much faster than with the stock dp/cat/exhaust.

I do not have boost creep issues.



Edit: There is a russian video on youtube that lets you hear the exhaust from an st205 (kakimoto)....just search kakimoto st205.

I didn't know the cat was part of the down pipe. But what I really wanted to know was how it would sound with no cat, no res, no nothing but a 3'' muffler.
