I have the Viva Performance CAI on my 2.4. They claim there are performance gains, but honestly it's not going to help or hurt your power enough for you to ever notice. Some people say they get better mileage with them though.what benefit does a CAI have on an NA car? i had a hard time justifying why i should buy one for my T5, and never did.?
Im not trying to dissuade you or anything but im wondering what the real world results might be?
I prettymuch want one because it sounds/looks cool.
just Dont want to expose my ecu or draw hot air from the bay....
Thanks! And yeah, I just didn't want to fool with it when I first got it all on since my car was inoperable for about a week already at the time lol.^ yeah it is very annoying. oil changes.
btw adam, just saw a picture of your car a minute ago in another thread... Looking good man, you gunna paint that trim or not?
No back pressure issues. There's a lot of confusion about back pressure on N/A cars, but straight piping won't hurt it at all. Lots of drone and the exhaust in general is a lot louder of course, but no issues aside from that. I'm probably going to do a 100% straight pipe on mine. Catless and all. I figure if it's too much, I can always add a resonator or something to tone it down a bit.Also I have seen videos from FosgateLife where he has a straight pipe from the first resonator back. Would anyone know of any back pressure issue or noise concerns with a mod like this on a NA engine?
Oh yes my bad mine was a 2005 which was what I was referring to but yes only the pre-facelift models. As far as problems go I remember someone had a lot of emission issues after chopping up the exhaust, I would recommend having a shop throw you on at least a smallI thought that only the pre-face lift models have the fiberglass packing in the muffler?
