Overview:

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

My 13lb dog loves these! But tears them up in no time!
Size: 15", Style: Rabbit
I’ve bought many of these, in different styles. My dog knows it as “bunny”, so if you tell him to “go get bunny”, this toy (or one of the other characters we’ve bought) comes back in his mouth. He loves to chase it, play tuggy, and whip his head back and forth with the poor thing. He turns these into threads hanging on to rope in no time. You’d think they would be super durable, but they don’t surprise him very long. I can’t rate higher than a 3 star, because I think they are made well but he’s just really tough on them and I keep buying one version or another because he loves bunny. LOL

Durable & fun
Size: 15", Style: Rabbit
These are great pulls, long lasting. The rope in different parts make it interesting to your pet. My only issue is, I did not receive the gray animal I ordered. It was substituted by a brown one. I’ve owned six of these. The dogs have loved them all BUT neither of them will touch this brown one. I’ve tried several games with it. They run, take a sniff, & leave it. This one was a wasted $10.

Keep these in our pet toy collection at all times.
Size: 15", Style: Rabbit
My 4 dogs love this toy so much I have them all over to play with. The inside helps make this adorable toy last for longer than most dog toys and for the price this means ALOT to me for the value of my money. This dog toy is soft and fun to throw around the house and not break anything as they chase it around. What dog doesn't love a squeaker toy also for an added bonus. The squeaker doesn't last long with 4 large dogs, but long enough I feel like for the price I paid.

My dog loves the Multipet Skele toys!
Size: 15", Style: Duck
My dog absolutely loves this toy and the similar ones (we had a snowman first). He rolls around with it and seems to be so happy. My dog is an aggressive chewer- and he destroys these toys within a couple of months. We have to take pieces of it away as they come loose, especially the squeeker, but he still plays with the rest. I wish it would last longer because he really loves it, but I haven’t found a toy that he cant destroy yet.

Terrible!!!!
Size: 15", Style: Duck
My 2 Australian shepards destroyed this cheaply made toy in 20 minutes! It's advertised for tough chewers, lol, the material it was made from is so thin, you could almost see through it. Don't waste your time or money!
