I am thinking of buying the pacesetter/catted y-pipe set-up from Texas speed along with the hooker catback exhaust.Do I need to buy o2 simulators for this y-pipe or does it have the o2 bungs welded in?My car is a 99 z28 m6.I am looking for a nice sounding exhaust that is not too loud, thats why I am considering the catted y-pipe to help keep the decibles down.If the ORY is not too loud with this combination, I would probably use this instead.Any other ideas or thoughts will definately be appreciated!

 

you should only need the sims if you are bypassing the cats or going orp.

 

A Y is a waste w/out headers. Save your $ until you get headers.

 

i have TSP's catted y and pacesetters - you will need sims or tuning to remove the rear 02's

 

My mistake, I meant to include the pacesetter headers also,does anyone have this combination and if so ,how loud is it?
