Hey guys and girls, i was wondering what the best size Cats are for a VT 5L? And what gains you get performance wise and sound wise ive got pacemaker extractors, twin genie mufflers now i just need the cats to top it off? any feedback will be appreciated. Thanks

Hi flow cats the same size as you pipework is now would be the best. No point in going bigger as they won't flow any different, but go smaller and they will be restrictive. Depending on what you have now, if the cats are still stock you will notice a gain in mid to top end, a more meatier, louder note and slightly better highway economy.

I can do steel hi flow cats at $195 each plus $35 shipping.
