I have been doing a bit of research on CAI as well as exhaust systems. From what I have read so far, it seems that the Volant CAI works the best and has received the best reviews. However, I have not seen any dyno info on this system.
I looked into a few other options, including the K and N system, which in fact, does have a dyno chart - http://www.knfilters.com/dynocharts/63-1563_dyno.pdf
. K and N claims an additional 17hp which seems great. Does anyone have any thoughts on this? Also, the Volant system looks as if it would receive much colder air vs. the K and N due to the design of the Volant box. With that said, I would think that the Volant would produce more HP due to the colder air. What do you guys think?
As far as the exhaust goes, I drive about 25,000 miles a year, so I don't want a loud system while cruising on the on the highway, but do want more performance, better MPG's and a bit of a growl when I step on it. Again, from the reviews I have read it seems that the Corsa exhaust is the way to go. But I do want to see a dyno chart or get an idea of what types of gains I can expect before I drop over a grand on the system.
If anyone has any ideas of what types of gains are expected or first hand experience I would love to get some feedback.
