Re: Warning to all getting their Wk2 exhaust done

I read it as the valves in the head, not the resonator...oops

Yes I did think of this but I didn't want to drop 1k on the higher flowing reso's with other stuff in place, what would be needed to stop the rattling is some reso's with a good amount of baffling inside and a x-pipe for sure and even possibly some larger piping up to the valves. This would cost a lot more for just a tad bit more noise, not something I want to waste my money on.
Where are these valves located and what is their purpose? Thanks

Re: Warning to all getting their Wk2 exhaust done

Location is towards the end of the exhaust system near the rear mufflers (about 1 foot before the rear mufflers and exhaust tips). Their purpose is to open as more acceleration is applied and to release more pressure that way, and close up a certain amount when less acceleration is applied thus creating more back pressure. They are also used for the ECO mode and stay closed a certain portion when ECO mode is active in order to preserve back pressure that allows the vehicle to keep sufficient power in order to run on 4 cylinders and kick back into 8 cylinder mode as soon as it is ordered to.

I have Zoomers cat-backs on my other 2006 Jeep SRT8. I just love the loud sound. I find the sound on my new 2012 way too quiet and subdued. Do you think aftermarket manufacturers will come out with exhaust products for the 2012 SRT8? It seems they will need the secret Jeep code to tap into all the computer technology.

Re: Warning to all getting their Wk2 exhaust done

Actually I'm sure its just a matter of coming out with a system that takes the stock valves into account and considers either replacing them with very similar setup just more hollowed out mufflers for a better sound. My 2012 seemed to have gotten a tad bit louder as I put more km's on it however I do understand its still not very loud. I however am happy with it because I'm no longer into driving a extremely loud daily driver.

I would hope that a good aftermarket cat-back would have more noise AND cooler exhaust tips that will be as attractive as the old center-mounted set-up.
