3 Inch Mandrel Bent Exhaust...what is your recommendation , with or without Cat Conv

I have a 3" system with cat to keep it legal, to my 03 GU. I have fitted NADS to it as well. It has made the troll a much more pleasant beast to drive, it pulls much better in 4 th & 5th now. It took a while to tune the needle valve to suit my driving style but it was worth the fiddling around.

Any suggestions would be greatly appreciated.

Thanks

Hey I was just wondering if you went ahead with your exhaust and how did it go? I'm thinking of one for my 2003 4.8.. I' not sure of the cost thou cost Vs benefits so on.

Quick question, will a 3" zorst from a zd30 01 fit on on an 03? I can get one for $300 but no good if it won't fit.

I think a 2.5" system will transform your 4.8, similar to having another gear
and a bit of a note as a bonus

Yes I cant see why not exactly the same motor, as long as both auto or both manual

Thanks TD will it mater if ones an auto and the other is auto?

Whoops and the other is manual

The pipe may route differently , but a visual check should confirm fitting.
ring an exhaust shop see if its the same part number

Just checked on ebay and they don't specify manual
or auto so by that I would take it they would fit
