Couple of days ago, just added 3inch downpipe, 3inch straight pipe, no resignator, added Super 44 series Flowmasters on my 04 GTP, sounds aggressive as hell. I did notice I lost a little boost from take off, (of course I know its from the 3inch pipes)but my top has increased & I'm liking it. Also when I drop down to a 3.6 pulley, I know that will increase my low end.
I had the pipes custom done! Bought the mufflers from summitracing.com. Lord knows the money I have saved vs. buying an exhaust system ready to be installed. Now I just need to get some tips, change my cat converter to a high performance converter.
Next I'll be doing a tune up with plugs & wires.
Then Drop to a 3.6 pulley
then a PCM card
Slotted Brake Rotors
High Performance pads
RAM Hood
New Shocks & Struts.
I may get headers I don't know yet
I'll be taking pictures along the way.
