Trying to get a little bit more than stock sound out of my 07 Tahoe. I have had flowmaster super 40 & 44 on other vehicles...I don't want another flowmaster. I have been searching all morning to find out what is the best bang for my buck on my 2007 Tahoe - Borla, Corsa, Gibson, Dynomax, Magnaflow??? The plan was to cut out the stock muffler and just add one of the above. I am not sure which to get or where to get it. I am leaning towards Borla and Corsa but they seem to only come in kits...I don't want a $900 kit just cut out the muffler and replace it with something that has some more growl. I also know the stock system is 2.75" so I would also need to probably find some adapters - so any insight as to where I can get those as well would be helpful. In All I am looking to spend less than $200. Actually, closer to $150 if possible. Thanks in advance for the assistance. p.s. If anyone has some insight into a used or cheap safari rack I am looking to add one to the roof. That will get me at least 3-5HP ha. Thanks.
