Im selling my catback and trying to design a true dual setup to work with that crossbrace.
Im considering using the existing y-pipe, and adding another custom y to the other end of the merge. Then running Dynomax bullets or Dynatech small ovals and turn downs in front of each rear tire. Expelling the exhaust away from the car to avoid residue buildup underneath.
Here's my question, for anyone knowledgible in the subject; Would the 4" merge flow well enough or should I ditch that y-pipe all together and get a true x merge?
if you run it out back, you have a few options. you can do under the axle, over the axle or a combo of both (like Bassani does). 3" over the axle can be done with stock routing, but requires more work than going right under the axle
