lgoodson@pacbell.net Posted May 24, 2009 Share Posted May 24, 2009 I have this 93 LT1 running now but I need the exhaust. It's at this moment a stock 300hp engine but I may add a cam and maybe some head work so how much pipe should I use 2 1/2" or 3" single exhaust or what? I am being quoted $500 to $700 minimum. Seems a little pricy Thanks for any advise. Larry Quote Link to comment Share on other sites More sharing options...
RUZN Posted May 24, 2009 Share Posted May 24, 2009 Use a 3" Magnaflow Exhaust, with a 3" straight pipe from the downpipe thats what I did.. but I have a Bender at work so took about 2 hours. basically my 3 inch is straight to the rear control arm. It then goes through as normal at 3 ich with sliiiight gradual bend so slight its almost straight =-) Quote Link to comment Share on other sites More sharing options...
lgoodson@pacbell.net Posted May 25, 2009 Author Share Posted May 25, 2009 Ya I am kind of leaning toward 2 1/2" head pipes and at the Y pipe go to a 3" with a Magnaflow. But I am reading on this site about the need to install a couple of bullet muflers before the Y to ward off any "droning" that would make the car un-drivable. Any ideas here Quote Link to comment Share on other sites More sharing options...
