Will gain anything from.....
Will gain anything from..... Installing a flowmaster merge in my TSP y pipe? I have a little rasp that I want t get rid off, would it be better to instal the fm merge or just put a bullut muffler inline immediately after the y pipe? Does anyone have any posted gains from the merge? Dyno or track time? Before and after sound clips?
If you want a better flowing Ypipe get the TSP. It might clean up the rasp but it won't get rid of it. If you just want to get rid of rasp then get the bullet muffler welded into the I pipe.

If you already have the newer TSP Y pipe, the merge is pretty close to a flowmaster from what I can tell. I have that Y pipe with pacesetter headers. Ran with no muffler for a while and then welded a Moroso spiral flow in the I pipe and dumped it behind the axel where the stock muffler would attach. I love my setup now!
