Thorley Header Project Update
whats some other good mods? i got my wife a 07 gxp and ive got a 02 gtp with a few mods on it and it spanks that gxp's ***, realy bad of the line too. i just want to make that gxp alil faster cause i love that car, i cant believe how good it sounds
Im gonna have an exhaust shop do mine so they can complete the exhaust setup im going with.Still undecided on the muffs though???MAYBE A CUSTOM DP SINCE HOGAN WONT SHIP TO CALI...
Really???Do you have a link????Same quality as Hogan,since i always see people with the Hogans(or is it a trend).Either way there a guy on here sellin his catless Hogan for $200
Here's the link: http://www.wbodystore.com/grandprix/...pes-p-219.html
$200.00 is a good deal for the catless one. I know I paid more for mine when I bought it. Mine will be for sale soon. Mine also has an O2 bung in it too. That's usually extra.
