True Duals X or H ideas
I believe Bassani also makes a nice but more expensive true dual system. Other than that they are all custom fabricated.
If you take your (2) 3" pipes from your y and run them into a twin 3" in and 4" out merge collector and run a 4" in/out muffler you can support 675FWHP with ZERO Loss.
I just did this and gained 20 rwhp over my 3" in/out borla xr1 race muffler. I make about 550 FWHP NA, and 750+ on n2o. This route saves a lot of weight and looks awesome if done right. I spent ~ 400 total including parts and custom labor.
