Anyone running straight exhaust with turbo?
 

As per title, keen to hear a video of anyone running a turbo 86 with just a straight exhaust.

I can't find a muffler design I like. And I wonder if it'll really be all that loud anyway.
I have a track pipe and straight front pipe as well now, but still with the cat in the stock headers, and I've gotten used to it.

A friend has a straight pipe on his sti drift car, and it's much louder than my car currently is. But I wasn't sure if this was because he was using a twin scroll.

Thanks in advance.

the difference in sound levels will increase dramatically once you change out the stock headers. the sti drift car is probably running 3" all the way back. majority of the turbo kits / supercharger setups on here right now aren't full 3" setups so they wouldn't sound as loud as an STi. take your track pipe off and turn your car on with just the straight midpipe, it should sound similar / a bit louder than what you would get with a straight pipe.

My turbo kit will be 3", from turbo to rear

Mine is a full 3" turbo back and its loud. I've heard it without a muffler and I wouldn't want to drive it any more than I had too.

2.5in with invidia q300, still very loud at WOT.

The exhaust housing will make some difference but 3" turbo back and no muffler is very loud, and drone is pretty bad.

I have straight through with a Perrin muffler and it's loud. I can't imagine what it would sound like without a muffler. Currently running 2.5" straight through off the turbo into a Perrin 3" catback

It's since broken in a little bit and become a tad bit louder. The drone is very noticeable at 100km/h and higher on the highway.

I just heard an open pipe 3" downpipe turbo FA20 last night and at idle its tolerable but after that it's earplug loud.

I run 3" to 2.5" catless/resonatorless but have a muffler and it is quiet at idle and just right everywhere else.. (except I have an open dump pipe so at WOT its insanely loud).

I think without a muffler it would be too much.

My 3" perrin with the turbo is very quiet just driving around, and not too loud at WOT. i have videos posted in the perrin thread.

My car is kinda nice sounding atm, but id love it being louder. I have plans of changing my nameless down pipe to a straight version, and maybe build a midpipe with a varex muffler + a muffler in the axle back versus my current setup which has a cat+res in the downpipe (op/fp) a res in the midpipe and the two res in the axle back.

Looks like a need a muffler :(

Yep, I think you do

If you value your eardrums you'll run one

i'll be running a straight pipe from the turbo no mufflers, maybe one resonator. should be up in about 2 weeks. I'll post videos when i get it.

It's been 2 years. Got that vidja? 😁

What's your set up? Any mufflers or resonators? If not, how's the drone on highway?

I don't think I have any current videos of the revs.. I'll try to get some up later (hopefully not in 2 years) ... I'm working on a few projects at the moment..

No mufflers, no cats, there are 3 high flow resonators, which really doesn't do much honestly.. it drones pretty bad on the highway, but I don't drive it that often so it's not bad to me.

I know it's an old thread but I have ptuning turbo kit with perrin 3inch back with tomei EL header. Would it be better to modify my exaust now or just have someone make me a new one. Thought about ptunings but dont want to spend the money. I liked how my car sounded NA in terms of how loud but turbo makes it much quieter.

Old set up was toemi UEL with perrin 3inch res. Any advice I would love feedback.
