Easy installation with all the instructions needed. Happy with this purchase for my 2006 350z.

Great product! Had no issues when installing and noticed more kick off the line in a track, have had it for about 2 years now and never had an issue. -'04 350z

Good upgrade! The car got louder in the lower and mid-range rpm's. Sweet, I love the VQ sound. Yes, I can feel a bit more hp and torque, the engine feels stronger. Went with Motordyne because the spacer is metal, and their reputation with this part is excellent, (although it's pricey). CZP had great service, quick shipping, and the part was well-packed. -'04 G35 6MT
