Re: Need Help on mod....
Hi guys, I think this topic has been discussed before bit I'm quite new to the site and I was thinking of the following mods.
1. Akro Evolution Line (full system)
2. pair valve or flapper mod
Now the questions are, does the 929 sound different with a full system that a bolt on akro, if so is it louder and throatier!!!
What does the pair valve mod or the flapper mod do, I've heard a lot about these two mods but cant understand the performance gains.
The exhaust is getting on tomorrow so I was thinking that I'd get either the flapper or the pair valve mod done too...
