I put Speedwerx triples on my viper yesterday. I started it up and it seemed a little loud. Is there a way to make it quieter? Also.. if anyone has had success with these pipes,, what jetting do I need. (I am jet illiterate).
I would call Bruce Schrader at Pioneer Performance for his jet specs, he was basically the guy that sold Majorty of these Speedwerx Viper pipes.Sled Ogre said:
I ran a set for a while prior to switching to CPR's and had very good luck with them simply using Bruces jetting. Unfortunatly I don't recall what they where something in the 165 range on the mains seems to ring a bell. According to my a$$ dyno I did not notice a huge differance between the 2 pipes but had to give the nod to the CPR's, But had good luck with both and it will definatly make big power over stock.
They are and will be quite a bit louder than stock but once your out on trail (hood closed and out of garage
) they really are not that bad IMO anyway. BTW if you don't have a rear exchanger added I would recomend one, The Speedwerx pipes supposedly out rev the agresive timing curve as do the CPR's but regaurdless I would still look to add one for those low snow condition / warm days. Once again only my opinion.
Hope this helps
