I'm welding in some Vibrant resonators behind my x-pipe Friday. I will shoot a video before and after. I've been dragging ass this week, and haven't had a chance to shoot any footage with the current setup. :)
yup ready to hear that before and after. decided to be brave and cut/weld into that xtreme huh?

Yeah man. I don't believe catted pipes are gonna give me the sound I want, so I'm gonna do the unthinkable and hack-up the venerable Corsa Extreme :confused::tsk::shrug:

I got ARH 1 7/8ths Direct Connect 3" to the Corsa Extremes. No cats. I mean at the right throttle % and rpm doesn't always sound ideal but I love how it sounds for the most part. You'll always get some rasp with catless setups but w/ the corsa it doesn't drone. Cold start is stupid loud. My GF was behind me and we went seperate ways on the highway she went north and I went south. While she was on the bridge going to the north section she could still hear me zooming away LOL.

If your ever thinking FI i'd just go catless and save yourself the $. Extremes + Headers at WOT is an amazing sound.
Can't you just change out the lead pipes in that case? Seems like a simple and fairly inexpensive swap to me if going FI.

Decided to keep the system as is. No cats and no resonators... I've put some miles on the car the last few days, and it seems to have lost a little rasp, either that, or I've embraced it :D

If you're running E85 I can't imagine the fumes from no cats would be that bad, right?
If you have ever been to the state fair and smelled carmel corn well that is what E85 smells like IMO. It is a sweet smell compared to the nasty gasoline smell. :thumbsup:

I thought the VP-110 race gas l use too run was some sweet smelling stuff, maybe not as sweet as E85 though.

It appears running E85 creates more water than gasoline and this causes O2 sensor failures because of sensor placement on some headers.

Trying to get some information on catted vs. off road header sound. I already have Corsa extreme exhaust which is kinda raspy. I'm looking at SW or SP headers and would appreciate input on how they sound catted vs. off road. From what I gather the cats tone the sound down a bit. Thank you.
Not sure I realized you had the xtremes too, lol. If and when you do put headers on, I definitely want to swing by and hear that.

I ordered SP catless headers and plan on putting them on when they arrive. I also have corsa extreme catbacks, if you're interested in giving it a listen feel free to PM me. :headbang:

Nah, I wish. Sorta torn between sticking NA or going FI, but either way any more mods are a bit down the line.

Also UPS was a bit late today but they came in. Pretty quick considering I ordered them from Beefcake at 10:00 AM on Tuesday. Hopefully AMR Automotive can fit me in soon!
