obviously it will not add 10-15 hp, maybe on the butt dybo. i would pm the guy selling and ask if it will fit your specific car. arent the 91 and 99 sentras cats different size?

I figured the ebay cat would be too cheap to be real. It looked like there wasn't much material that could be packed into such a small space.
I was only looking for a stock replacement to pass smog, so I just ignored the bling and the supposed hp gains in the item description
