FREQUENTLY ASKED QUESTIONS
Cat Back Adapter
The cat back adapters are simple slip adapters that allow connection from our downpipe to the remaining exhaust system left on your vehicle.
For example if the remaining exhaust on your vehicle is OEM/Stock you would want to select the OEM/Stock cat back adapter.
If you have a 3" cat back you would want to select the 3" adapter. Same again for 2.5" and 2.75".
We have built our downpipes this way so if in the future you want to change your cat back exhaust system you would only need a different size adapter and our downpipe will still work.
