Like the title says my SGT just got a 2007 STI now I don't know if the exhaust it has is a aftermarket or not but sounds like it is and it also sounds like it has a aftermarket blowoff valve. What I have is a 2009 pontiac G8 with CAI,HSRK,LP MOD,X-Pipe 2.5" mod, Pypes axlebacks. Secondly what I have is my 98' Z what I have on it is K&N FIPK, ported tb, UD pulley,160* therm.,LS6 Intake,Pacesetter LTs,3" ory, hooker catback with a cutout on the I-pipe and mail order tune from FROST, oh by the way the Z is a M6. Tell me what ya'll think and why.

 

One way to find out! The Z would get him. For sure. Don't know about that G8 lol.

 

assuming traction isn't an issue, and that he doesn't have his turbo dialed up without telling you.

i would think you can take him.

 

I think you have the wrong section.

 

you'll walk him with the z..he may hang or pull on you through second but then it's goodbye.

 

Yep.
