Who are you getting to tune the SM4??

Looks the goods

Im sure it would sound awsome Wayne! Just be careful, not sure if it applys to you but while on my odd reading expiditions today (and not to alarm you) they warn not to pound her too much without a tune as the JDM models have those hypereutectic pistons and dont respond well to detonation! Like i said, may not apply and hopfully not, just a heads up!

im sure having an exhaust will make the car run richer as the sensor is removed from the cat. So i cant see this doing any harm to detonation..

Sounds wikid though wayno...

one of the best sounding wrx's ive heard in a LONG time.

just don't drop a skid in the wet

norm builds primo exhausts. not shown is the reducer from the 3" to 2/12" is all flanged off so no cutting no welding just easy on/off when the time comes to change muffler or return it back to standard. epic success!

What skids, tail out, rear kick or all of the mentioned dont know
what your talking about

It also allows boost spiking if its not controlled, but having the autronics maybe it will control it fine.

Jeff "Type25", Gavin "STIV6325", Jono "JMAX" and countless others dont have any probs and they also have JDM Spec C's.

So i wouldnt be too concerned mate

how can running rich cause boost spiking??

I don't think it would suffer as badly, but it is a known fact that some GD's can turn up the wick with a free flowing exhaust. Boost control duty cycle from factory is set with the backpressure of the oem system in mind. Having said that the 204 isn't exactly a restrictive system.

Two thumbs up wayne!!! I didn't notice 3 cats on the dump I thought it was just the one off the dump then a tiny resonator then that plastic pond looking resonator in the middle (which is a straight through unit too!).

Maybe check the NAIOSC website, theres numerous people saying they changed the exhaust and had the EJ257 pistons shit themselves due to detonation. Increased exhaust flow from the engine to spin a turbo at a greater rate causing the turbo to be able to create more psi. But like i said, maybe having already tuned it, it will be fine. Also like wayne said, other people have not had any problems so im sure he wont either. Now i demand either,

A) Youtube footage or;
B) AHG day date.........so i may attend!
C) Where this video shop is you frequent so often,so i can hide in the bush secretly and listen
