I am planning next week on Hi Flow cats along with headers etc. on my Gen 4 and need feed back first from those that have the Belanger brand Hi Flow cats installed on their Gen 4. Are they reliable and do you like them over all? Do they allow flex with engine movement? Im aware of other brands such as Random and Roe but would like your opinion of the Belanger cats. Thanks.
