I'm finally in the final stages of getting my 1987 5.7 GTA put back together after replacing the stock L98 with a new GM crate 350, 330 hp engine equiped with a Vortec intake manifold, TPI, new injectors and rebuilt TH700-R4 transmission. The last thing to add is the exhaust system and I'm asking for suggestions.

First off I have installed a set of SLP 3/4 inch coated headers with new cross over pipe and Y pipe collector. By the way, I had a machine shop weld a stainless elbow on both air pipes to line up with my stock emission tubes. I've just ordered a Dynomax 15622 high flow catalytic converter with air pipe return. I was thinking of keeping the stock 3 inch intermediate pipe and just change the muffler. Suggestions are appreciated.

Thanks,

Vance
