i was wondering what the best cold air intake is out there for my99 lightning. i would also like to know which exhaust system works well with it thanks

 

the PSP, JDM, or JLP intakes are all great and will meet your needs 100%. Bassani is the best catback available (aka most expensive) but there is also magnaflow to consider ( a couple hundred cheaper i believe). they are both better than stock, although the bassani seems to get the most thumbs ups on the sound. but if u are looking for performance, buy a 4 or 5 # pulley instead of a cat back imho.
