CUSTOMER COMMENTS ABOUT HEADERS

Exhaust Headers

Pete Hall about the Iperformance Header for 96-02 Cavalier/Sunfire Z24
"...I can tell a noticeable difference in power increase...
...it was a pain in the rump to remove the stock manifold, but it was fairly easy to put on the Iperformance header.  Well, I am pleased with the product and I thank you again for being the distributor and all the help you've given me."

Aaron Ward about the Iperformance Header for 96-02 Cavalier/Sunfire Z24

Adrian Salve about the Iperformance Header for 96-02 Cavalier/Sunfire Z24
"Get this header."

Elias Fernandez about the Iperformance Header for 96-02 Cavalier/Sunfire Z24
"TRUST ME you will be on cloud nine when you get that bad boy on and if anything you will have to watch yourself for the first few days."

Rob Klyne about the Iperformance Header and Cat-Back Exhaust
for 96-02 Cavalier/Sunfire Z24
"Well I had both (RK Sport and Iperformance's) and the RK header was garbage as far as I am concerned. If it came with a collector that wasn't so small maybe it would be better. With my RK header and exhaust I ran a best of 15.6 with the new header and exhaust both Iperformance I ran a 14.9."

Ian Clark about the Iperformance Header for 99-02 Cavalier/Sunfire
with 2.2 liter OHV Engine
"I  have recently purchased a Iperformance header from your company. I must say WOW. What a great piece. I purchased this header to replace the RK Sport one i already had on the car, which leaked so badly there was more noise from the front of my car than the rear. The Iperformance header is great, no leaks at all.
...It has made the power band much smoother and wider. It seems to have put
back the mid range torque the RK lost. i will have no problems recommending this product to the others in my club. Thanks for selling a truly great product. Its great. There is a night and day difference between the Iperformance and the RK header I had before it."

Ryan Bodnar about the Iperformance Header and Cat-Back Exhaust
for 96-02 Cavalier/Sunfire Z24
"I have the Iperformance header and catback and I absolutely love it. The sound is great, and there's a noticable difference in power."

Dustin Enns about the Iperformance Header for 02-Current with Ecotec Engine
"I recieved the header for my ecotec last week and put it on yesterday. What a difference from just a header. Well worth the wait...
...I love it."

David Gomes about the Iperformance Header and Cat-Back Exhaust System for 2000 Cavalier Z24
"I just wanted to say thanks for everything. It all came out great. I have no problems with the header vibrating loose or the cat-back. The cat-back system fits perfect and it is not as loud as the Magnaflow i had before."
