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 I had a Mustang at least 04 challenging me in sound, and a round body caprice.
I had the pipes custom done! 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 & Structs.
I may get headers I dont know yet
I'll be taking pictures along the way.
Mr_gtp!
