    Hadn’t seen anyone review these Rev9 cats yet so thought I would:

    Pros:
    1. Titanium
    2. Affordable
    3. 200 cell
    4. Car sounds stock in sport mode until valves open
    5. Cruise speeds sound like stock
    6. 2.5 lbs vs 13 lbs
    7. Perfect fit
    8. Nicely finished
    9. No codes (I did use spacers provided on request) but they said it was unnecessary.
    10. Sounds amazing in Race mode. It is significantly louder and decel pops and crackles are accentuated. (Big smile here)

    Cons:
    1. Doesn’t change the pitch of the sound
    2. A lot of work if looking for a different pitch bc you won’t get that.
    3. The spacers they provided didn’t work with my mini cat extensions(I bet they would worked fine without mini cats with or w/o extensions. I purchased ones that were approximately 2inx2in elbows. Cheap. I didn’t wanna take a chance of having to take bumper and exhaust off again.
    4. Driver side 02 sensor doesn’t have a lot of slack. Had to remove one screw hanger under left air tube for more slack.

    Overall: worth it if your looking for the same standard, amazingly awesome, Ferrari sound at a higher decibel level for about $1500

    Titanium cat pipes? Either that’s a typo or you probably should get an exhaust from a company that knows what they’re doing

    Yep Titanium. They did eventually throw codes though

    So, I must ask, why didn't you want to do a new exhaust? Which WILL change the tone, and be more F1? Or are you doing this in stages, and then will keep the high flow cats on with a new exhaust down the road?

    I’d just read that changing the cats gave some more volume, so I wanted to see how they worked out; I like the tone and it’s hard to hear exactly on videos. The car sounds amazing and louder now only when I want it to be. I’m a little hesitant on changing the muffler bc I don’t want it to be loud on the freeway to work. Planning on Kline, but wanted to look forward to it too.

    Cool. I've heard pretty much every system on these, as I'm in the business and a dealer for all types of parts. The Kline is one of my fav's for the price. Even with the exhaust you don't get drone, it's just much more glorious sound. You may find after a bit you'll crave more and the exhaust swap will be the cherry on top.

    Kline is one of the more quiet aftermarket companies. Minimal difference volume wise than stock if you just change the muffler portion. You can also get their Inconel Button which is their valve controller to better control volume.
