the search didn't net me much info, so i'm posting a thread instead.
i'm curious to find out what the majority of 20b'ers are doing for exhaust. are you sticking with 3", or do you have it tapered larger/split to dual on the way out? i would like to know, and it could be a good reference thread for people with future projects.

is anyone running a 4 inch exhaust?
i am currently finishing everything up on my project and just trying to find a decent sounding muffler that has a 4 in. inlet/outlet.
i know magnaflow, flowmaster, and borla make them, here are some links for the hell of it:

http://www.magnaflow.com/02product/02race.asp
http://www.flowmastermufflers.com/race.html

i dont think the japanese companies really make a full 4" muffler, some are close though.
if anyone knows of any others i can pick from, or has any other idea's, i'm all ears.

so, if you could post your exhaust setup (maybe motor porting, what turbo/s (if any) that you're running would be great also.

Thanks!!

 

me and sillbeer are both using the border 90mm exhaust, with a 115mm tip.

 

I'm using the HKS TI racing 100mm exhaust with a 4" DP. I added 2 4" bullet mufflers to help quiet it down a little.

 

4" main split into a pair of 3"...

Open DP

 

Same here

 

Ted, is that still NA?

 

Yep, we started with that anticipating going turbo.
NA was 2" (Racing Beat tubes) into 4" "collector" mated to the rest of the 4" exhaust.

I'm using a 4" downpipe, into a 4" exhaust that splits into dual 3". It's made of 4 pieces (downpipe, one piece to the mufflers, and 2 mufflers) and put together with v-band clamps at the turbo, downpipe, and mufflers. I am running a fuel cell to make it fit in my fd though. If you want to see pics, I can post them for you, and if you are interested in one, talk to Rich at Auto Illusions. His website is at http://www.autoillusions.com and he goes by the name "autoillusions" on here.

 

I set up a cheap exhaust behind my header made from 2" Racing Beat pipe and Rotary Engineering glasspacks. It needed to be quiet for a while, and it worked out great, but doesn't flow as much as your setups. I'm going to upgrade to something bigger and louder later.

 

how excessively loud is your guys straight 4"?
is it deep or shitty rotary sounding?

 

I've posted a vid clip in a thread somewhere.

I need to make another one since the mufflers have been changed out.
