Hey guys. Now with ricing gas prices i am no longer going to purchase a LT1 but instead i am going for the LS1 solely because my friend is getting 18mpg without ever getting on the highway. The first thing im going to do to this car is exhaust. For me a car has to be or have four things. 1. Be Quick. 2. Handle good. 3. Look Good. 4. Sound Good. I think the stock Ls1 f-bodie has all of those except #4 so heres my dilema. I want an cat-back that is LOUD, with an exhaust note that is a mix between Muscle Car and sports car. A rumble down below with a little bit of rasp up top. Right now im considering LM, Love the sound but i figure it will get old fast,GMMG, Sounds damn good but pricey and i dont know how loud it is when cruising, and Corsa. Corsa is the only Cat-back i havent heard in real life. I am considering corsa because i love the looks of it, the price isnt bad, and that special sound cancellation may keep it from droning on the highway. I love the sound of all LS1s. Ive never heard one i didnt like. What i want to know is what you guuys think of the corsa system, how loud is it compared to other systems, does it drone, and if you like the sound of it.
