I have 6-2-1 headers from motorsport with a 2.5 exhaust and turbo muffler also from motorsport. I think it is too loud. What can I do to make it more quiet? Would a 2 in aluminum pipe with a different muffler help? Looking for suggestions.

I also have the same exhaust system. My best approach to this do-it-yourself system was to take the car to a performance muffler shop and point to the car and say fix-it. They sealed up the whole system at every connection, and evenr had to alter the 2-1 header piece to make it shorter(for clearance). It really made a difference. Obviously, because of the headers, the exhaust is much louder than stock. Yet I can live with the results. Good luck.

You can also have a 2.5 glasspack installed inline. I did that to an Integra GS-R we used to have after adding turbo muffler and it quieted it a lot.

I also bought a 6-1 header from Motorsport with their 2.5 inch exhaust tubes. Too LOUD!. I went to a muffler shop and had 2-inch alum piping installed and a non-turbo muffler. Much better now. Performance does not suffer much by this change.

I just started looking into prices for this part of the car(260Z). Is the 6-2-1 any better then the 3-2-1 header system. noisier? less restricting?cheaper? Adaptability?
