That is all.
Good suspension will cost a lot more then a 2.5k catback A non built non tuned motor as mentioned by 45SET will see very little in the way of gains from just catback, i only saw a 4kwatw increase in peak kw with a powergetter and header with a 200 cell cat, also ended up running a lot richer in the process. The only thing you are assured of with an aftermarket VS custom exhaust is the exhaust sound which why i went powergetter (also got a great price )
