Message	Hi, I was hoping I could get some experinced based feedback on exhuast sizes. I am looking at getting a twin system but am not sure on how much size makes a differnce with regards to turbo spool and performance. Iv found a well priced 2.25 inch dual system and was going to match it up with 3 inch dps and most likley test pipes or high flow cats. I belive iv heard that going to 3inch makes a huge differnce but it may have just been an opinion. Please let me know what you think DF
