i got ya...i guess if i did he "custom" route id have to have them drill a hole and weld in another bung....i may just save the headache and save up for the UR DP with the 400 cell but even then again thats 500+ and so close to a APR tune

APR Stage 1 = $599 (with sale)

Downpipe = $300-550 (Depending on brands and options)

APR Stage 2 = Free


If you get a downpipe, there is no reason not to get the Stage 2 upgrade because APR offers it for free. However some shops will charge for labor...

I am running a Eurojet TBE, No Cat with a RAI o2 sensor spacer using the middle sized jet. No CEL.

Ultimate Racing DP with 400 cell CAT: No spacers, No cel's, No tune.

Mine's been flawless..

Any idea if either of the CATs will pass a sniffer test? AWE says their HJS CAT will pass a sniff test, so that will likely be the deciding factor for me, despite the price difference and my preference for a 3" system.

the o2 sensors are factored into the tunes cbfa or ccta if u were to remove one it would cause problems unless u customize the software.

easier to leave o2 alone and use apr tune

I don't know what Canada has but in the USA sniffer test results are judged on a state by state basis.

Search by USA state and DEQ (Department of Environmental Quality) and you can see what it takes to pass emissions.

In general, west coast states are difficult to pass emissions with tuned exhausts.

Yeah, Canada varies from province to province as well. In Victoria (where I study) there is no emissions testing at all, while in Toronto there is a visual, readiness and sniffer test. I can find out what the specific numbers Ontario looks for are, but without data regarding emissions of the respective DP/CATs, it's hard to make use of that info. AWE says their DP will pass the sniff test, so I'm using them as the benchmark.

It sucks that Godspeed doesn't make a cbfa down pipe or I'd get one and the spacer.


Oh btw, which sensor(s) need to have spacers
