turbo back is better if you get a 4in turbo back you get 4in pipe for the turbo all the way back. With a cat back you keep the stock down pipe. I would save up for turbo back.

Ya, if you get a 4" turbo back system for an obs, Its usually with a 3" downpipe and 4" after that.

THIS is why you change the downpipe on the 95-97 trucks:



Beware, it's not a very easy process to change though.

a 3'' dp would also be much easier to put in than a 4'' inch... and ya it would be better to get rid of the stock dp for sure!
