I know, I know. This has been asked a lot of times, just like what kind of oil to use or how much air for the tires. My question of all F3Limited owners is, what manufacture do I buy from that makes the exhaust somewhat louder but not too over whelming? Did you remove the primary muffler or just replace the secondary muffler? Also what manufacture you bought from and why? Were you pleased with the sound after the farkle? Thanks for all that give me your recommendations.
