I returned the Remus Sport I had put on my car because it was a loaner. I went to a reputable local muffler shop and had a custom exhaust installed with Magnaflow mufflers and tips. The sound is more pronounced and throatier than Remus. The whole system weights only 24lbs. The quality of their work is excellent and the whole setup costs $500. Custom midpipes would've been $200~$300 more which I opted not to do at the moment. IMO this is a very cost effective way comparing to name brands that costs well over 3k.
