Question about which flowmaster merge to use
Car: 02 ss convertible with 1.25” bmr springs/koni shocks
exhaust : 1 3/4” pacesetter headers, some random pipe, 3” bullets.
Question: what is the size of collectors of pace setter 1 3/4” headers and which size flowmaster y merge do I need to connect between pacesetter headers and fbody spec magnaflow catback.
Current exhaust:

Usually a Y is defined by the tube sizes feeding it. If you have 3" pipes from the headers, the inlets of the Y will be 3". The outlet of the Y will be whatever size the catback system is.

After the merge I have a Magnaflow bullet muffler in the I-section which goes into a aftermarket catback. You definitely don't want a 3" out. Either 3.5" or 4" with 4" being a little better. I had a shop weld it in and they used a small reducer of some sort

I would be interested in seeing more pics from different angles

Thanks for info. I’m lowered and worried the 4” part of pipe may bottom out.

My 99TA had the Mufflex / Flowmaster dual 3 inch merge collector to 4 inch out. It had a 4 inch to 3 inch reducer to hook up to the SLP 3 inch Dual/Dual catback. The merge collector never scrapped over 130,000 miles over15 years. My car was lowered about 1 inch with SLP Eibach springs. On nasty speed bumps the I pipe would scrap.
