The Maximum Flow flows either direction, allowing for easy installation. Single 3" Offset Inlet, Single 3" Offset OutletPart Number: 21630HKR
The Hooker Maximum Flow muffler actually flows 99% and produces more horsepower and torque than a 2-1/2" open pipe. The Maximum Flow is constructed of an aluminized steel case with stainless steel internal core and uses a high temperature packing material to absorb excessive noise while allowing a mellow powerful sound. As with all absorption type silencers, the Maximum Flow will be most effective for sound control with lower compression (8.5 to 1 and lower) motors with conservative Camshafts and with applications using catalytic converter(s). The Maximum Flow flows either direction, allowing for easy installation.

Excellent Dahlia Seeds — Huge Difference in Quality
Size: 1-Pack, Style: Zinnia Dahlia, Size: 1-Pack, Style: Zinnia Dahlia
Excellent germination rate and very fast growth! I planted these seeds side-by-side with another Dahlia seed packet from a different seller on the exact same day under identical conditions, and the difference has been amazing.
By day 23, these seedlings were already thriving — healthy, vibrant, and growing quickly with a very high germination rate. The plants look strong and vigorous, and I’m extremely impressed with the quality of the seeds.
If you’re looking for Dahlia seeds that actually perform well and establish quickly, I would absolutely recommend these. I’m excited to see them continue growing and blooming

Size: 1-Pack, Style: Zinnia Dahlia
This package had more than the pkg that was supposed to have 4000, but they are coming up slowly. It is dry here, I have been watering , just enough to get the ground wet and they are scattered, but some are coming up. I also watered the space supposedly where i spread seeds from the supposedly 4000 seeds pkg. They are not coming up as much!

Didn’t get a review on the garlic powder
Size: 1-Pack, Style: Zinnia Dahlia
The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch
