Give your G8x M3/M4 more sound and power with our high-flow catted downpipe. Fabspeed Motorsport's engineering team consulted with HJS Motorsport and chose the largest HJS catalytic converter that would fit the G8x chassis. This guarantees the most exhaust flow, reliability, and sound. Our Sport Cat Downpipe will flow 93% of a 3'' straight pipe, all while providing emissions compliant performance and NO check engine light. There's no need to run cat bypass pipes!

SOUND:

Our Sport Cat Downpipe does an excellent job of subtly increasing the exhaust volume and deceleration pops and burbles, with no increase of unwanted interior drone. For a more aggressive exhaust note, add our Intermediate X-Pipe.

POWER:

On our in-house DynoJet, our high-flow Sport Cat Downpipe made max gains of 23 ft/lbs of TQ at 3,200 RPM and 20 WHP at 6,500 RPM. That’s 23 crank HP! Take a look at our dyno graph and you can see that power is gained throughout the entire power band.

FEATURES:

  • Fits all BMW M3 & M4 (G80/G82) sedan/coupe vehicles including Competition Models worldwide (2021+) (RWD & AWD)
  • Adds an impressive 20 WHP and 23 ft/lbs of TQ
  • Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel
  • Light weight design saves 2 lbs / 0.9 KGs compared the factory system
  • We use a German-made HJS HD tri-metallic 200-cell catalytic converter for the best performance and reliability
  • Laser scanned and CAD designed for perfect OEM fitment using Ametek Handyscan 700
  • No CEL (Check Engine Light) guaranteed

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!
