Sr Viper D&D Barker and OSP Muffler reviews

[Gongshow77]

Looking for owner reviews on the D&D Barker and OSP pipe for the sr viper. Just wondering the owners thoughts on each pipe, basically which is louder and which one provides more hp? Thanks guys!

I'd be willing to bet they are both within 1 hp and both within 1 decibel for noise, I actually think that they both use the same muffler itself, it looks that way at least. They are both very loud and will draw a lot of attention..good or bad. If you're set on one of the two, just go with whatever one you can find cheaper

I bought my viper used and it came with the osp can and it was extremely loud. I sold it and bought an Ulmer / SLP can which is perfect. Near stock dB and great build quality. I'm sure the osp can has good hp numbers but I don't want to be that loud.

I love my osp its loud and good quality I can't speak for the d&d, I have yet to see one in person.
