Canadian Hummer Club Forums

Want to let everyone know my experience.  

Cats were dead, my truck is a US vehicle so not covered under warranty.  Queensway hummer wanted $2500 for replacement.  I went to a local guy and got magnaflow hi flow cats for 390 installed tax in.



symptoms were, car was bogging under hard acceleration, also just didn't feell ike it had the power, like it was struggling to accelerate or even maintain speed.



Stephen at Tech Tune Exhaust in Etobicoke did the work.  416-801-8147

this is the guy that I keep recommending people to.. Steve is great, he has done work on a lot of members trucks, including mine and Markus' H1 as well..



Also if you need any regular Hummer H2 or H3 work done, check out Steve and Jeff at Master Mechanics in Brampton, they are both GM techs with lots of Hummer experience and if you tell them Derek sent you, you will get a great deal, they can be reached at 905-455-8888.



for all exhaust, Steve at Tech Tune is GREAT!!
