Default Dual Exhaust Idea/Questions

What do you guys think about this idea for my 90 L98.

Hooker 2151 headers into a cat at each header (is there room for a cat right at the header collector on each side?), all of that spliced into the Corvettecentral dual exhaust set-up, with free flow mufflers?

Is the CorvetteCentral dual kit anygood? should I just have a local do the dual set-up?

I will be watching this as I am thinking of the same thing.....

But as for cats....I believe on a manual you can squeeze em in but with autos it gets a little tricky...possibly not possible..but don't take my word on it. There are many guys who have done it...I will let them chime in.
Good luck!

I think you'd be better off going from the header to 2 3" RandomTech bullit Cats and then into a LT1 catback system with an X-pipe in place of the resonator. The LT1 catback is 2.75" stock (compared to 2.25" L98 stock) and 3" with most aftermarket kits.

Just a suggestion.
