Is it safe modding the MSP? since its kind of a new car, first of its kind, and it still has yet to be perfected.. would it be safe modding it and voiding the warranty? ive already had some problems w/ my car such as subs short circuiting, vacuum plug or something got loose and car stalled, and today i had the wierdest thing happen.. i was in the highway in 5th gear going around 60... rpms under 3000, as i bring the rpms to around 3000-3500, my car starts to rattle vigorously, im bringing it in for a check-up asap.. im want to get an injen intake and possibly apex's cat-back but if the MSP is known to have a lot of problems often, i may need the warranty.. so if you people have been having some random problems (stock setup) plz let me know of them? advice.. anything would be appreciated.. and i did search a lot so.. dont think i didnt research before writing this thread..
