    Lol she realizes that they weigh a lot and that awd system's parasitic drag is astronomical right? I was logging my buddy's Saturn Sky Red line once and came across the v8 version. He walked it hard on the freeway. Just bolt ons and tune on the sky. But the way that 4.2 sounded... ugh it made my penis move.

    a rubber mallet is going to be your best friend.. don't pay anyone to do it, you'll get ripped off.. its time consuming to get it right
    Yeah I couldn't get both pipes in there. I tried one at a time and the driver side fitment was really good - nice height, no obstructions with the O2 ports, resonator was centered, and bottomed out in the connectors. I tried the passenger side alone - low height, resonator was twisted side-to-side and tilted upwards. Tried them both at the same time (with and without a rubber mallet) and could not get them seated in the connectors - they were either falling off the collectors (header end) or barely in the resonator sockets. Rotate too much left or right and you completely obstruct the O2 ports - doesn't matter it still didn't align trying that way.

    I marked and rotated each side in small increments to find that perfect fit - no success. I feel another diatribe setting in thinking about it...

    Good news from SW...they are shipping new catted pipes and trimmed elbows. I only got high level details but it seems the welds around the cats were the problem.

    Yea, I have the catless setup and had to fight with mine as well. I wasn't smart enough to complain about the oversized elbows and ended up trimming them up myself. I love the sound of mine and hopefully you will too

    Re: Stainless Works Exhaust Install - 2004 CTS-V

    Got the refitted cat-pipe leads and elbows over the weekend from SW. Just started the alignment tonight - the leads go into the resonator...finally! It is still a wrestling match though. I have the driver side completed and will finish the passenger side tomorrow. I had to trim 1" off the driver side elbow - SW warned me they left a little just in case. The passenger side looks like I will have to trim 1.25 - 1.50". I hope to have it all done and fired up by Wednesday or Thursday at the latest...wife is out of town and I'm on kid duty. I've been waiting 3 weeks so a few more days...WTH.

    I think you will be in good shape. Hopefully SW is looking more carefully with their product out the door. The little bend they put in the passenger side cat pipe made all the difference. An exhaust shop would have no problems with installation. I had to cut 1.5" off the passenger side elbow and got a good fit. If I really wanted to be picky, I could cut 0.5" off the passenger side long pipe and get it perfect wrapping around the differential but I'm saving that if/when I need a new rear-end. The alignment came in really good - satisfied so far.

    I'll take some final pics of the install and share them once everything checks out. I'm hunting around for a tune with this one little mod.

    My wife doesn't know the difference between mods and repairs. As far as she is concerned, the "V" is constantly broken

    Hey did you run into an issue with reinstalling the dipstick, I had to make a spacer to get it to mount up right.. it just wouldn't return to the stock position with the header flange in the way

    I kind of intentionally blur the two. Gotta replace the motor mounts and oops new headers...
