Default Exhaust LSx inputs [Pics]

OK so in my quest to make a California state legal exhaust, I'm at a cross road.

I have a C6 Z06 exhaust that with a little fabrication can be made to work. Drivers side is completely doable. Passenger side is the one in question. Pics that follow....





As you can see I'm hitting the frame. My idea is to grind down the side and re weld a bolt further back. Making a bolt in all 4 corners. Given the heat and vibration, do you think this wise?

Or should I scrap the idea and just stick with longtubes? I have it my head that I want a 100% functional vette that will get me thru inspection.

With the little bit of contact you have there, I would hammer additional clearance in the frame rail, which already has a nice dent in the right place from GM. If you used a torch and a square peice of metal as a dolly it would look factory.

We ended up with a C5 manifold on the passenger side in my swap---holding my breath the BAR ref will approve that.

I like the idea. I'll talk to the shop. Good input. I have a set of c6 z06 manifolds and ls3 set. I wanna stick with z06 so I hope frame will work.

You can try taking a little off that ear, with that ans the dent in the rail have plenty of clearance.

Nice way to have a great exhaust system.

I used the 98 corvette OEM manifolds and they fit great.

Just don't go nuts because that ear has to hold the stud and that part of the pipe closed with some force.

Then take car when tightening it I think you will be OK.
