    I have a Tubi exhaust but would like some more sound.

    It seems like decat pipes would be a simple and relatively inexpensive solution. I'm also seeing decat pipes with a built in small resonator..? As well as high flow 200 cell cats.

    What's the advantage / disadvantages of these options? I like the idea of better throttle response and the small gain in power typically had by eliminating the secondary cats but is this as much of a "no brainer" as it seems??

    Any advice or help would be greatly appreciated.

    Thanks in advance..

    I have Tubi, stock cats and fabspeed headers, sounds really good, I do not know what gives you more "punch" the headers or the cats, but If I would get one or the other I will get the headers, that way I kill two birds with one stone, because the headers will eventually fail, it is just a matter of time.
    Now, changing headers cats and exhaust is the ultimate sound!!!

    Great feedback! Thanks! I just got my car and it's a 2000 model year with only 7400ish miles. The general consensus is that eventually however the stock headers will fail?

    What is the advantages / disadvantages to the test pipes compared to 200 cell cats or these test pipes with the small resonators built in to them I've seen? I think adding headers down the line is a good possibility for me so I think I should buy the correct test pipes (200 cell cats) that will work best with headers.

    I don't want the wildest sound level possible but I definitely want the thing to scare women and children ;)

    How does the sound level change between test pipes or 200 cell cats? Will I need to reflash the ecu either way or would the high flow cats not cause cel to pop up typically?

    Seems like dumping the secondary cats is indeed a no brainer though.. I guess I just need to better understand the sound level difference between these options.

    I had resonated test pipes on my 360 with Tubi. Hated them and everyone else said they sounded bad. They were small glass packed resonators in place of the cats. They were louder than the stock cats but a much deeper note. The Ferrari F1 sound was gone. Also instant CEL. Switched to Hyperflow 200 cell cats and sounded great with lots of great comments and no CEL. Mine was euro spec so no pre cats in the headers. It was loud but not over the top. Go for headers and sports cats with your Tubi. I think you will be happy.

    One of my headers started rattling at 25k miles (look at http://www.ferrarichat.com/forum/360-430-sponsored-yellow-compass-group/519271-weird-noise-cold-startup.html ) and I decided to put aftermarket ones and the sound improved drastically
    I got CEL codes which I "kind of" fixed with mini cat extenders (after 400 miles I got codes and CEL), but I think they will come up again.

    Great info! Thanks! I'm glad I asked about this as I was leaning towards the resonator/cat delete pipes.

    I think I'm going to go ahead with the test pipes. I feel like if I want to add headers some day I'll need the cats, but for 3 grand maybe I should hold off and see how I like it with just the Tubi exhaust / test pipes. I think I could sell the test pipes at that point and recoup the majority of the money spent on them.

    Thanks to everyone for the info. As a new Ferrari owner this help has been priceless.

    Stainless steel wool packed resonators would be good. But NO to glass packed.
    Test pipes will be LOUD!

    If you do test pipes, take into consideration that your car will smell quite a bit. It'll smell like an old car. 200 cell sportcats will sound a lot like test pipes but without the old car smell.

    With the test pipes, the car will be significantly louder. The Sport Cats add a really nice tone to the set up without adding too much drone or noise in the cabin. With the test pipes you're pretty subjected to a lot more noise inside, and the gas smell is more noticeable - like an old muscle car.

    you only smell fumes if you are standing directly behind car not in the cabin

    Ugh...OK. I don't like the idea of any kind of smell that's for sure.

    Travis, do you have videos of both the test pipes as well as Sport cats? Do you think they sound the same basically when used with the Tubi exhaust? What is your pricing like for Sport cats you'd recommend?

    I'm glad I paused before ordering the test pipes.. I definitely don't want that stench in the car. It's not worth it to me especially since I could just change the rear box to get a little more noise.

    Also, do I need any new sensors etc to install in the new cats should I go that direction? Just want to consider all the costs involved and I noticed the bungs welded in the cats or do they just accept the cars original sensors?

    We just had sport cats and Fabspeed headers installed on what had been a Tubi only 360 Spider.

    Definitely louder, and DEFINITELY sounds fantastic. Keep in mind, all of the above is highly subjective. YMMV. Yes, we have the MIL on, but had that before from the Tubi. I think it's going to take an ecu tune to eliminate it.

    In my opinion, worth the money. But forget about sneaking in at 3am. Ain't happening !

    There is definitely a difference in decibels between running sport cats vs. test pipes. I will PM you over some more information on them!

    Not the best videos, but shows some idea.

    Thanks for all the help.. I really appreciate it.

    How can the difference between 100 and 200 cell cats be described? I've seen both and I can't quite figure out how the sound changes between them? I understand the difference from a functional standpoint, but is it reasonable to think 100 cell cats like the Agency Power pieces will be louder than 200 cell Fabspeed cats?

    It's hard to compare catalysts as cell count aside you also have duration (catalyst length) and the overall diameter to consider. As we can't directly compare the two, consider weighing the quality of the components.

    We use HJS catalysts, extremely high quality tri-metallic pieces made in Germany. Tried and tested, they are a high end solution to increasing exhaust flow while minimizing the chances of getting a CEL.

    HI Travis,

    Working on the install of my new cats and noticed 2 bungs in each of them for o2 sensors.. Guessing this is needed for Euro cars? My question is which one I should be installing my original O2 sensor in? On the stock cats the sensor was located before the cat (between the cat and header). But I noticed in the instructions on your website says to use the bung located after (between cat and muffler) the cat now. Hoping you can clear this up for me.
