exhaust performane and install

How many horses would i get out of hooker 2055s, catco cat, and the hooker super comp. ho tpi catback? Is this a pretty easy install? does it include any welding and if there is how much?

I didn't realize they made an HO TPI kit, I thought the HO kit was for the L69 motors, either way, the only difference among the cat-backs is the way they hook to the cat.
The HO kits have a rectangular flange on the I pipe that hooks to the cat.

With all that, I would say 30hp is a good estimate.
