Catback exhaust opinions? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Calidrifter · 08-21-2012, 02:22 PM

After reading that article I have a few concerns.

1.) The story doesn't have a V.C. number. AB stands for Assembly Bill meaning that its not part of the vehicle code yet.

2.) Specific range for our vehicles. Is the FRS/BRZ classified as a LEV, ULEV? What affects do the current intakes have on the AFR of the car and does this move it close to or out of the acceptable range for our car. I know that on my S14 with injen intake/tanabe exhaust the AFR was almost always on the edge of the allowable amount.

yeah, I'm no legislator, but from what I can tell it passed in both House and Assembly, and was approved by the Governor (Governator) in 2010. Not sure what else needs to happen before it goes into effect...

the takeaway for me is, as long as your ECU isn't throwing codes you will likely pass. Several of my cars have catback exhausts and the smog check guy never looked twice at them, all he cared about was visual under the hood, gas cap passes the pressure test, and the emissions part on the roller/dyno (which will go away). Net effect is I think it will be easier to pass smog for most of us. If you have removed cat or have non-CARB intake yeah you will probably have to swap it back to pass, but that hasn't changed.

The catback should be enough to swap back to stock for emissions testing, no? It shouldn't affect your warranty at all.

I personally picked the SRT headerback (or catback in your case) because I love how clean it looks.

I guess the original point of this thread is now void, because (to my surprise) when I got out of the shower this evening there was a brand new ISIS exhaust sitting on my front porch. Early birthday present, I guess!

How loud is it in person? Is it deep (not farting noise?). Was the uneven burnt tips fixed?

Anything that has direct connection to the exhaust will void the warrnty of the part - but in all seriousness, not likely.
There is no reason that the exhaust will damage any part of the car including the engine - it gets better airflow than the stock. [they could claim that the "back pressure is too much that it pulls out too much air from the combustion chambers and messes with the air/fuel ratios" but that seems like a load of bs]
But if a dealer hates you for it, go to the next dealership for work. Some dealerships cares, others don't.
TRD exhaust will be 100% hassle/haggle free.

But I'm still waitin on the Greddy

Only headers would need the CARB. Exhausts only needs to meet the sound limit.
