Pipe in new or excellent shape from turbo to cat- converter

I'm also restoring a 1984 zx turbo, and looking for exhaust system. the best I found is HKS, but i didn't like the mufler. it cost around $316 with free shipping online. and you can get a beter mufler from ebay around $100 inclode shipping. so total might cost you $500 instaled.
