On a car with a muffler, i will take the bet that it is no better than stock. Sure you have equil length primaries that are 31 inch long tube. But with a muffler those benefits are marginal. The key is the primary diameter.

And they will be heavy. Ssi's are a mild weight savings over stock, and most of that is due to the cat.

If you are building a race car, get headers. Skip the heat and save the weight.
If you want heat, stay with stock, even with a pretty hot 3.2 or 3.4.
Any more power, go with flipped 993 headers (for heat), or go with larger 1 3/4 headers.

My honest opinion.
