10 Bucks says you have either a bad earth, or the gearbox earth is not connected correctly.

Yeh pod makes awesome WOT roar, screw exhaust I say lol (4 banger NA sound crap imo)
$400 not bad. Including manifold? Wait Northside? Just beware we have a member on here that had bad experience with them, just letting you know whether you decide to do it or not.
MR2 was destined for that 2GR!

Here's a dumb arse question that I have been wondering for a while.. 'WOT' - is that 'Wide Open Throttle'???

^ Nothing to do with Captain Sensible and 1981?

/\ yes WOT is exactly that Pedal to Metal etc etc lol
and silly me for suggesting the afm, i could have sworn my N/A  had a AFM but its been a while now.

Well AFM or air temp sensor or MAF or MAP either way they all ultimately measure air flow regardless :/ we're just being touchy technicals haha
WOT - waste of time. Cars...

True it does make a very nice, BUT with it, the WoT sound gets quietened a lot with a better flowing exhaust, the stock manifold (headers) are said to flow pretty good as is. I know this from my last car aN13 pulsar, dropped a pod on ... loud WoT sound .... gave it an exhaust, quitened the WoT but increased the power greatly ... ... the main reason I will be doing the exhaust, is because the bowl is swolen, and choking the engine some ... bigger is better .... Have heard another MR2 from the guy that has reccomended this place to me (jumping subjects pretty bad, sorry, tired) and I heard it running on his ... rather nice and breathed well.
 
Anyways, will talk more ... when im not so tired.
