How to get my car a bit louder?

[1991NSX]

When I get home in a few days, I will put up some sound clips of my current setup. Currently, I have Cantrell headers and Taitec test pipes going into the GTLW. If you want me to, it would be no problem to reinstall my stock cats for comparison. I can also do a comparison inside with and without the engine cover. Whatever you want. I haven't actually heard the exhaust with cats so it would be interesting to hear for me.

That is very generous, but I'd never ask you to go through that much trouble. If you can do a sound clip of what your car is like now - if you'd like, that would be more than enough for me.
Thanks for the offer!

What about loosening a few of the bolts going to the muffler to induce an exhaust leak?

I'd indeed recommend going with test pipe's.
They sound nice and will free up a little power.
