These pipes are LOUD. Pretty much just straight pipes. I will have to figure out a way to get a soundbyte recorded and on here. The Spinwurkz site has one but it deosn't do it justice. Also the fairing screens I bought on ebay got here, but don't seem too "formed". I just should have bought the raw material. I'll be putting those in soon, but will wait to post new pics till all my spikes get here.
