What made you choose this particular product?
We were attracted by the product because of the optional 30" muffler which gave the exhaust a lower sound and not a raspy sound.
Is this your first time buying from this brand? Did you consider other brands?
Yes, this was our first time buying from aFe. We did look around but ultimately went with aFe.
Was it easy to install? Any installation tips that will help others?
It was pretty easy to install but do have a squirt bottle with soapy water to make the exhaust hangers slide into their rubber fitting easier.
Once you've had a chance to use the product, did it meet your expectations?
Yes, it increased airflow on the truck and gave it a nice sound.

What made you choose this particular product?
Talked to Nic about lowering the car and he suggested the aFe CONTROL springs. He has them on his ZL1 and the price was right.
Is this your first time buying from this brand? Did you consider other brands?
Yup and I had considered Pedder's coilovers but they were to expensive to get here in Canada.
Was it easy to install? Any installation tips that will help others?
Nick and the guys from AGP did the instal. Message him via their website.
Once you've had a chance to use the product, did it meet your expectations?
Good initial mod for anyone with a 5th gen.

What made you choose this particular product?
Performance and Fit, also didn't see anyone else running this set up so I wanted to try it out. They had proven dyno numbers showing HP and TQ gains. Why not.
Is this your first time buying from this brand? Did you consider other brands?
No I had a Takada Intake for my 2004 Acura TSX and was happy with the part.
Was it easy to install? Any installation tips that will help others?
Was an easy install, didn't take long.
