FS: NHP High Flow Cats
 

I have had these cats for about 4 months and about 3000 miles (maybe less).
I have decided to just go back to OEM and I'm selling them. I have the gaskets and the O2 hole plugs in case your o2 position would be different.

If you have a 97-99 you need the NHP headers to mate to them otherwise you should be okay according to the Maxspeed website.

Asking $650.00 shipped.

Thanks
Chris

Why are you selling them?

I'm picky about the sound and with a stock muffler I had a raspy noise when cold. I didn't feel like trying different headers so I am just leaving it alone...apart from putting an OEM S muffler on.

These are still available...make an offer.

Thanks

These are still up for grabs. I'll include the headers too to if need be. They are Maxspeed's original ones (pre NHP branding).

Chris

Just a bump on these. Please make an offer.

Is there any way to mount them to chinese headers?

They will mate up but they also just sold at last.
Thanks,
Chris

Do you still have the headers for sale ?

Any pics of it ?

Sorry, these have sold.
