Deeper exhaust

I went to a local muffler shop and had them weld in Magnapacks with a 14" long body and 4" round about 6" behind the H pipe. They finished off the rear with stainless and some Maganaflow tips for around $350. At first the sound was good but the volume was a little disappointing. After about 500 miles the volume fixed itself and the sound improved also. Yea I know this is worthless without sound clips.

I had thought about that a lot, but the Pypes MM system is $300 at brenspeed. I think that's the selling point there.
