    Stainless Works Exhaust Install - 2004 CTS-V

    Here is the stock exhaust system removed.

    Muffler delete, yeah it drones at 2k rpm and under.


    Here is a pic from shadybx7 and his install with a SW exhaust. That thread can be found here http://www.cadillacforums.com/forums...n-exhaust.html

    Here is what I received: Look closely at the elbows and compare with above.

    Look how the rear aligns with the elbows and with mufflers on the hangers:

    Here are the long pipes as it wraps around the differential - I don't have it lifted fully but it wraps around rear-end no problems.

    Here is a pic of shadybx7 headers wrapped:

    Here is a pic of my headers: wrapped and painted using DEI

    Here is my problem aligning the catted lead pipes from the headers to the resonator. This was after hours of rotating in every possible way to fit both pipes centered into the resonator and with the resonator centered and level. I'm squeezing those pipes together with about 0.5-0.75" pulled from the sockets at the headers. The resonator is at a good height close to the chassis but not touching. Take a look at that offset.


    I have experience with exhaust systems but claim to be no expert - cars are a weekend hobby, and this is by far not my first. So for those that think this is a weekend DIY in your garage thing...My car has been "garage queen" for a week. I can tell you that I have been in touch with SW and at this point...they are responsive but no resolution on any of my fitment issues. I started a thread when I ran into a sheared header bolt and it expanded to further frustrations with the fitment of the exhaust. That thread can be found here: http://www.cadillacforums.com/forums...g-headers.html

    So many choices on what to do next but I'm leaning towards spending all that savings on this purchase of system and taking it to a shop to fix some very obvious fitment issues. I don't have the equipment to bend a 3" SS pipe to get a good alignment and since it takes a shop to do that...I might as well have them trim the elbows. BTW, I was told that this fitment is very precise and encouraged to keep trying. So I called a few fellow enthusiasts to see if they were up for a challenge. Well, I got back my "man-card" after no success on the fitment. I got one more expert coming by to give me the final word before I take it to shop or...if SW comes up with a resolution - whichever is first (umm, it's been a week).

    Thanks for taking a look. I tried my best on this install.

    Danm, So I am going to get mine professionally installed then. I would rather just pick it up after a few hours of someone else installing.

    thats bs to spend that kind of money and have to get a exhaust shop to install it, a bolt on kit should do what its avertised.. bolt on!
    if you have followed instrusctions and the system is not right , return it. i can understand slight alignment issuies with a kit, but having to spend coin to have a exhaust shop re do pipes is rediculious.
    subscribed and hope you get it figured out.

    Agreed, SW should make this right. As it stands, this looks like it's going to wind up being more expensive than Mangaflow, or whatever. So why not just go with that instead of Stainless Works????

    Re: Stainless Works Exhaust Install - 2004 CTS-V

    Damn, sorry to hear about this. for what it is worth, my resonator is deff not level, its kinda torqued alittle. my drives side connection pipe is slightly shorter. you deff dont need to bottom out the connection pipe on the header to get a good seal.

    you elbows look completely wrong. Did you show SW the comparison pics??.. I got my system used from the fabled Naf, so it was a early system.. they dont sell many from what i can tell but my fitment is good and i have never scraped(well it is stock springs)

    BTW Very nice job on the header wrap. :thumbs: they smell terrible on first start up, nasty cookies.. smokes like crazy


    my connection pipes look different,

    Yeah, they are very responsive. They agreed on the elbows and took a look at the pics I sent with my concern on the resonator fitment. It's not very clear for them to see the issues I'm having from the pics. They want to see photos with a fitment that matches their photos - I can't get those angles because I'm on ramps - not a lift.

    Just so everyone knows...this thing is going on my car! Excluding elbows, the pipes are not waaay off, the fitment from the headers to resonator is expected to be close enough for an installation shop to fit correctly. Unfortunately, this was not a DIY for me. I got a final pair of eyes on this and the work required to get it installed correctly is beyond the tools in my garage - I don't have the ability to crimp and bend 3" pipes.

    From the videos and testimony, the SW sound is amazing and in the end...I'm hoping it's worth it. I don't want to discourage others from getting the SW exhaust. I just want to inform others of my experience so they can plan better. It's going to be quite memorable driving with headers wide open to the installation shop. Maybe I can get some videos of it. I plan to document as much as I can with any adjustments to the system.

    Update...catted pipes & elbows sent back to SW. They have an LS engine and are going to test a few things to see what (if any) problems there are with the catted pipes and resonator fitment. They have been very responsive through emails and phone calls. The downtime gives me time to fix/replace unrelated stuff with the V...new seatbelt, dipstick, exhaust hangers, Gorilla black lug nuts, and OEM replacement bolts for stuff I broke.

    No, didn't drive it. I got some quotes from some local shops and the only one capable of customizing it for a perfect fit came to $400 - he has a mandrel bender etc and could fabricate a new pipes included in the quote. Other shops wanted to charge $200 barring any fitment issues.

    hopefully that gets resolved.. did they change jigs or something WTF
    They should receive the pipes sometime this week. I had to study the pics they sent me for a long time and I wrestled with the pipes for hours. I don't suspect it is their jig.
    I think it is a welded section just before the cat on the passenger side lead pipe.

    If it had a sharper angle, I think it will line up to connect the resonator - we'll see what SW comes up with

    I am just hoping they don't mess mine up lol. I. Won't be very happy it my mechanic gets everything going in and calls me up to tell me it doesn't fit. That would suck.

    i agree 100% i got under the car yesterday tried to get my :: aligned better, just want to clarify that the center resonator has to take up all the slack in the exhaust, if the inlet/outlets on the resonator are not fully "bottomed out" so the exhaust piping is almost touching the resonator, you're doing it wrong, don't give up until its bottomed out.. deal with the tips last after the resonator/midpipes are torqued down.. allowing the rear elbows to sag slightly will yield more aligned tips..

    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

    Hell, I would love to do it myself, but my girlfriend would come out every 5 minutes to ask how much longer, and bitch about how long its taking, and how she is tired of watching the kid and blah, blah, blah, blah... I would happily pay the $$$ to avoid that.

    What year? I was looking for a B7 RS4 or S4 along with the CTS-V but they are still waaaaay expensive. I just love how that 4.2L V8 sounds with a nice exhaust.
