well if it were me for first mod, I agree with Lid and exhaust but since I just bought my car, I will get a lid by summer but before that I am going to be installing a Dynomouth exhaust on my car in about a week or 2.. Cheaper then SLP's Loudmouth and in my opinion sounds better...

 

Is there anywhere where I can hear what an SLP or dynomouth sounds like? A website or something I can download? Thanks.
