I put new intermediate exhaust pipes as mine were severally rusted even though the car has 13K miles on it.
I had been patching the holes with muffler bandages and hose clamps for years.
I chose to keep the exhaust as close to stock as possible. I do miss the rumble and I think the car is a bit less peppy.
But I kinda like how quiet it is. It still has the original muffler and tail pipes.
BTW, there is a guy on Ebay trying to sell a 5k car, original exhaust system for $2999.
If mine rotted this bad after 13k, I don't think the 5K system is that long for this world.
The last picture is the after market pipes installed.
