performance mods

does anyone have suggestions for after market exhaust systems that are not too noisey but give significant hp increases???

i build custom mufflers in any configuration for the Vx. What are you looking for?

I ordered a muffler and the stainless steel intake for my 1999 vx. from you last week, my question, is muffler coming with 2 outlet attachments for dual exhausts or a single outlet??? and what is your best estimate of ship date..getting anxious to put these goodies on...byronius
