tanabe 3 inch dp to a corksport res/test pipe to the piping from an obx 3 inch exhaust i got for free. chopped the obx muffler off cuz it was huge and put an apexi n1 evo muffler on the end. makes my straight piped 5.8 bronco sound like its on mute.

 

Corksport turbo back exhaust!.. Had them on for years.. Trying to get dual apexi's or gt spec though..

 

kakimoto

 

full racing beat REV TII turbo back.... its a very nice and quality product but it sounds almost stock. dosent sound like a catless rotary at all. super quiet and stealthy, and does sound great for a street exhaust... but this is america, and I have a turbo rotaty. that **** has to be loud and annoying. gonna hack out the big resonator, and go to a single exit as soon as I can.

 

Corksport header to Corksport 3" pre-silencer thingy. Cheap eBay 3inch catback with fart can muffler. Loud as **** on my half bridge n/a. Not impressive at all but I thought I'd contribute haha gonna cut it up for my 2 4 inch slanted blast pipes lol **** it.

 

Heddman headers+x-pipe+ apexi dual n1
Think about changin it tho to a NASCAR boom tube

 

^ Do it!

 

I have just a straight pipe from the stock header

 

I'm just curious but do any of you guys get the O2 sensor DTC with your exhaust setups? If so, did you run a simulator or a mini-cat spacer?

Mine is catless and it throws the O2 sensor code for days.

 

There is no o2 sensor after the cat... the ecu has no idea if you have one or not. you probably just have a bad o2 sensor

 

Aaaaaaah **** that kiddo beat me it!

 

I recently replaced the O2 sensor and still get the DTC for it.

Don't mean to hi-jack, just thought I'd ask here since it seems pretty relevant.

 

racing beat headers to blown glass pack to stock mufflers was the best sound i had heard from an n/a 13b, i tried it with another set of stock mufflers and it sounded like **** guess you gotta get lucky and have your mufflers be worn out just the right amount haha

 

3" SS DP, RB Presilencer, HKS Catback. Open w/g

It's fairly quiet. I would definitely recommend adding a RB pre-silencer for anyone wanting to cut down on the noise levels of the car

its still loud when the w/g opens though

Rb header to rb presilcener to a Trust sp cat back. Love the tone.

 

long tubes to 3" y pipe to 4" blast pipes. merica.

 

Where the sound clip?!

 

once it's running i'll post one up. so maybe a few years from now i'll have a sound clip

 

Sounds fair

 

 

Figured I throw mine in.

- S4 Turbo Mani w/ T04B25 Hybrid
- Racing Beat 3" Down Pipe
- About 2 feet of 3" piping going to cat back
- Apexi GT Spec cat back, has a 2.5" inlet at first muffler
- Goes up to 4' piping and out the fart can

Why cut down from 3" to. 2.5"?? Then to 4"? Why????

 

For the rumble. Didn't want it to sound like every other FC with 3" straight pipe.

 

Should have just stayed 3" till the 4" blast tip cause now your exhaust can only flow a much as the 2.5 cause it's choked off just a suggestion

 

2.5" should be enough for my power goals. Also, I'm getting boost creep at ~5K RPM with the ported wastegate wide open.

Aaaaand... I'll just drop this right here.
