Fabspeed sport cat review

Just received my downpipe from the good folks at Fabspeed. It took about 2 weeks from order to delivery. It came incredibly well packaged. The downpipe is beautiful from end to end. Almost a shame to hide it under the car. Install will be in the next day or two and I will try and take more pics and review the sound.....

Okay. Pipe installed. 2 amateurs can do it in under an hour with a lift. Upper V-band clamp obviously tricky. We just used a punch to tap it around until it surrendered. Fit was flawless. Several extra minutes spent making sure everything was perfectly mounted. Zero leaks. Amazing sound under startup and rev range. Almost no noticeable noise difference while cruising. Five star product even if a little pricey. Thankfully we only need one. Lol

I have a 10 second rev video on my Iphone that turned out great. PM me a number and I'll gladly send it

Looks nice, OP.
Do you know the advertised the hp / torque gain for the dp? Everything I've seen combines DP with other upgrades and it's impossible to tell what dp does on it's own (which is what I'm considering). Thanks!

Fabspeed's dyno graph looks pretty close to my butt dyno results. It's a small but noticeable increase. Most gains felt in the low RPM range. I consider the sound improvement worth the cost alone. For me, the sound is perfect now with the pipe installed and the ASD removed. I know it's cliche, but this is how it should come from the factory

Cat Spec (diameter and density)? Power difference before and after? CEL?

I didn't dyno before/after or at all yet. I can tell you that the difference is plenty noticeable. Turbo spool is slightly more audible. Awesome burble increase around 4k rpms and on redline upshifts (DCT). I did a launch control takeoff a day or two after install and the torque increase on launch was enough to upset the traction control. Car aborted the launch and gave me a clutch warning. I haven't tried LC again since. Just brake boost and gas seems to be better anyway.

Zero exhaust smell. I've stuck my face right up to the pipes. That's why I went catted. Great tone, plenty performance, no downsides. About 3-400 hard miles w no check light.

Face up to the exhaust? That's dedication! Thank you for the review and we're glad you're happy!

Is the M2 emission certification level EPA or CARB?

Only asking b/c of this recommendation...

https://www.magnaflow.com/support/te...ght-converter/

If an OBD II vehicle is built to meet CARB standards, then it requires a California certified converter. For example, one significant difference is that NYS will allow EPA (Federal) certified vehicles to use a non-CARB part whereas California does not make that distinction.

Which I am reading as if the car's VECI is CARB then it is best to use a CARB cat.

I know most are installing the cat for sound but is there a concern that we could generate enough heat by tracking the car to melt the cats? Or is the M2 cat beefed up too like the coolers and oil sump?

Thanks for the chart.

Is the diameter of your dp larger than or the same as that of stock dp?

I am asking that because I have a big concern it will trigger CEL eventually in 2 or 3 years.

The cat being larger in diameter can offset its lower density to some extent and improve the flow capacity in the meanwhile. I heard a few companies do that in some other applications.
