Dealer is helping me pay for my new Evoflow Cats after 2 years!

Figured I would start a new thread to show the install/review since there doesn't seem to be a whole lot of info on the Evoflow cats yet. I made the discovery last week that the car that I've owned for 2 years had resonated straight pipes rather than catalytic converters, and the CEL's I have been chasing for just as long may be related. Original threads here:

After making the discovery, I went cat shopping and found these: http://www.evoflow.com/fer_360.html . $1700 MSRP, 200 Cell, no (cat-related) CEL, as opposed to Capristo or Fabspeed that want twice as much or more for their 200 Cell cats. Long story short, after some good advice from @dm_n_stuff , I emailed the dealer that I bought the car from and after a few back and forth emails (where I laid out all the issues I had with the car upon delivery that were supposedly fixed and the many thousands I have spent on the car), they agreed to pay for half of my new cats if I shipped them back the resonators. Good deal IMO since the resonators are most likely worth a few hundred bucks at most.

My new cats will be delivered on Friday, but I've already pulled the old exhaust/cats. I'm replacing the exhaust mounting bracket (bargain basement find at @Ricambi America ) because mine had been welded together, I also spent about $70 getting all stainless steel hardware and exhaust clamps since the original crap was all rusty/stretched/bent. Of course replacing gaskets and spacers also..

Here are the original cats-no core, just resonators, like a Cherry Bomb glasspack.

Good point. I'm usually pretty assertive in getting what I want, but I had not even considered the legality of the situation until you mentioned it. Don't think a dealer would have even considered assisting in a car purchase from 2 years prior if it wasn't for that. Thanks again. Owe you a beer if you ever head north.

Awesome! Even though it's been neglected as of late, I LOVE my Z06. I've had it for 6 years and it's one of the best cars I've ever owned. Can't see my getting rid of it for anything other than a C7 GS or Z.

No smog testing in my county, or else I would have noticed this WAAAY sooner. My main issue was the mechanical issues caused by straightpipes, the legality issue was leverage. I've probably dropped about 10 grand in parts (plus Lord knows how many hours) fixing issues that it was not supposed to have upon delivery, several that even the PPI didn't catch (plus they cleared the codes before the PPI which pissed me off). Didn't want to push too much for stock cats, they most likely would have been used, more expensive, and would have had less success without a legal battle, which I did not want. Didn't really want the bulky, problematic stock cats anyway. Mine's a 99 so the pickin's are super slim. Plus I got it from a mom n' pop used car dealer, not a F dealer. I'm happy with the result, it was what I was going to negotiate down to anyway. I started with them paying $1700 for the cats, they offered to pay half and I took it. Plus I was able to negotiate the price of the cats down some also.

 

The Evoflows arrived today, they look to pretty nice, good welds, will be installing tomorrow and taking pics

Wow so I guess I forgot about the thread and never updated. I suck. The cats are decent for the price, sound decent (my car is still plenty loud), but my biggest complaint (and I have communicated this to the owner of the company) is that they don't seem to be entirely stainless steel, but put together from a mish-mash of different pipes and then polished, which makes me question their longevity as opposed to the higher-priced cats on the market. In fact, I filmed a short video to send to him to show the differences between the sections of metal between the welds. You can also tell by the coloring that they are not made from the same grade of steel, and the grades are not consistent between the left and right. You can see this easily since my crossmember is still off the car today. Evoflow did offer to replace the cats for me, but at that point, it just wasn't worth it to through the hassle of pulling the exhaust again, so I'm living with it.

Yes, I'd be interested in knowing that my feedback was taken into account. Upwards of $2000 is still not "cheap" for what these are, even though they have a lower price point than others on the market. That being said, even at their price point, you are right to expect a product that was as described, and I was a little disappointed....not that it really matters to their functionality. They offered to make it right, but it just wasn't worth doing the job again.

 

Thanks for the explanation, now that the material issues are resolved, I feel you offer a quality product that is a reasonably priced alternative to others on the market.

 

To be completely honest, not a huge difference that I noticed, maybe just smoothed the sound a bit...BUT I also have a Gruppe M exhaust, which is just enough to qualify to be called an exhaust, so it's still plenty loud. I do have the original headers, don't plan on replacing them unless necessary since they don't have the precats from factory.
