I have the MST intake but have paired it with a foam Ramair filter. Any suggestions to improve the factory dump / blow-off / recirc valve sound on pressure release?
Injen is legal and comes w the sticker in California? Sorry about the question but I just can’t find any and I’m stuck in stupid Cali where mst is not legal
personally i went with the INJEN because it shows the most hp gains vs the others and the sound is just about the loudest. it also comes with a heat shield and i love that it came in a wrinkle red finish!
