I have the L98 TPI with the G92 option and dual cat exhaust system. Everything is stock. All the research I've done hasnt really answered my question. Flowmaster's website says all their cat back kits are for single flange 2.5 and 3 inch single cat cars only. Magnaflow's website shows the same part number for all v8 camaros. I don't want to go down to a single cat setup either. Regardless of single or dual cat, will either of these kits fit? Am I SOL? Surely I can't be the first person to pose this question. Any advice would sure be welcomed. I'm dyin' here!

 

The RPO code for dual cats is N10. G92 is the RPO for the differential. I've gone down this path as well. Except I was looking for headers and Y-pipes. As for a cat back exhaust, I have the SLP loudmouth 2, which is designed for a 4th gen F-body. It was almost a direct fit. You have to modify the exhaust hangers or swap to 4th gen hangers and you have to modify the intermediate pipe a little, it ends up being too short.

 

Well I ordered the Magnaflow kit #16829. Hopefully it'll fit. My father said he liked the sound better than the Flowmaster kit after I showed him some youtube videos of each one. And since it's for him anyway...
