Here is my issue. I recently acquired a Fast Intentions Catt-back from another forum member. Very good deal, so I didn't have to spend much for it.

It is one of the OG design Catt-backs that uses the one piece Magnaflow Resonator for the X-Pipe.

The exhaust is still great quality, sounds good. Tips and everything look great.

My only issue is that I feel like the internal baffling of the Magnaflow Resonator is past its prime and it's no longer completely doing it's job. I recently made a trip to Cali, and combined with my HFC, there was some droning from around 3-4k RPM, which is not a huge deal.

I also feel like the exhaust is a little loud in general, when just driving around town.

So, I wanted to know what Resonator Fast Intention uses for their X-Pipes, as I am considering having a shop cut off the Magnaflow 1 piece and welding on the 2 separate bottle style resonators.

Do they use Vibrant? Magnaflow or other?

What are your thoughts in general about adding different resonators to my FI X-Pipe.

Does anyone know if 2 Vibrant Ultra Quiets would fit?

Mods - feel free to move this to the Exhaust sub-forum if needed. I figured I would start here since the exhaust/intake subforum doesn't get that much traffic.

 

Anyone know what the design is on the inside of this thing?
