Decat Pipes and rusty chassis

[andypg]

I had the chance to have my tuscan on ramps the other day and under close inspection noticed rust around where the cats are. The rest of the car is totally clean of rust,which i,m happy about. The cats have to come off in order get to the affected area so i have decided to go down the decat route. So my questions are, what products do you recommend to treat the rust and prevent it coming back. Also which decat pipes do you recommend to use. Thanks. Andy.

I'm getting quite a lot of heat up through the gearstick,so hopfully decatting will help in that area aswell. Will decat pipes make that much difference with standard cans that have not been sleeved?
