Want to go catless - help!

Hi,

I have stock headers, and a bassani x-pipe sitting in the garage, waiting to be installed.

Here are my questions:
1. What part would I need from the headers to the x-pipe?
2. Is it bolt in?
3. Performance gain from going catless/x-pipe(HP increase??)?
4. Sound change (have B&B PRT's)

Thanks

Halfway!

X should mount right up to the stock flanges on the headers. Did you consider going with long tubes ever? It will be louder and you will pick up a few horses

I didnt think the x-pipe replaced the cats. If it does sweet.

Any other help or confirmation would be appreciated!

Depending on how the x-pipe is fit into the system. I have seen where guys have torched out the cats and just welded the x-pipe in their place, is that how yours is set up? If you eliminate the cats the sound will definitely change. I have American Racing LTs with no cats and B&B bullets and my car is loud. Hope this helps some.
