it has a 4" custom exhaust... not sure what make etc

 

With a 4" exhaust, it'll be LOUD with a capital L, if you remove the cats.

 

Either swap the exhaust for something a bit quieter or get a second silencer custom fitted on the mid pipe.

 

Another option to release a few horse, would be to fit a tubular manifold, these replace the stock manifolds AND the first cat.

The first cat on NA's is a b*stard to remove done 2 now and bolts are very fragile so tend to sheer off best idea is to wd40 them a good 2-3 days before you plan to remove to ease the job up a bit
