Loving my pipe on Spare parts

The cat gets 5 stars for this price. Delivery was great. There are no gaskets in the kit, I didn't expect that. Haven't fitted this to the car yet but it looks like the picture and just like a car exhaust.

Pros
  • Easy to use
Cons
  • Discontinued model

An economical replacement that works!

Easy to screw on. I've now driven over 1000 miles and had no problems starting the engine and no check engine lights. The only thing that would be an improvement would be to send the necessary spacers along.

Pros
  • Easy-to-read control panel
Cons
  • Negative impression

Good price on parts

This exhaust did not give out any codes after installation. It is designed to replace the factory standard hose and transducer. I bought one from California shipped from the Philippines and it basically had a hollow transducer. fucked up ! This Walker exhaust is a real find. Driven more than 5000 km without faults or problems, good price.

Pros
  • Pleasing
Cons
  • Not sure

because the cat was sick. before i bought this i went to .

I bought this for my 2006 Chevy Cobalt SS because the cat was bad. Before I bought this I went to my local muffler store to see how much they would charge to just cut out the cat and replace it and they quoted me a whopping $650 so I went straight to Amazon to see what I could find. I stumbled across this item and it seemed like it would work so I bought it and it arrived earlier than expected. The witch was very nice. the assembly was perfect, fit like the others, was very satisfied

Pros
  • Perfect for outdoor activities
Cons
  • Not all will fit

TUBE IS SMALLER THAN STOCK! Enormous performance loss! Enormous loss of kilometers now too!

UPDATE: I lost 4mpg from 24 to 20 after 2 cans of gas. I will try to come back. Future updates are expected. ORIGINAL POST: 2" tube, 2 1/4" SPARE PIPE! My wife's HHR isn't a hot rod, it's a 2.4-liter automatic LT model. 20 foot burnout. No longer! I installed this center tube and the result was a HUGE LOSS OF TORQUE AND PERFORMANCE WITH THIS PIPE! I basically eliminated all the benefits I had from taking it and then some. It was a clean and easy install with a liquid key the day before.…

Pros
  • Absolute Legend
Cons
  • High Price
