BMW G8x M3 / M4 Valved Sport Exhaust SystemSound With Free Flow Downpipes: Besides the quite strange grille setup, the G80 is a killer new M car, but like most, the sound is lacking. The Factory exhaust for the New G80 G82 BMW M3 4 does not deliver the goods. We fix that with our single 3. 5 inch mid pipe. This mid pipe incorporates an equal length design that allows for a very enjoyable high pitch sound experience without having to modify your OEM rear section. This mid pipe connects to OEM

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

The snap to put them together.
Color: Coal Black
This came in handy in the foyer. I didn’t want to see the door from my couch. I must be weak found it hard to snap them together. I kept 2 my daughter took the other 2.
