Got a friend that's doing DT Headers and SPD catback and will have a custom midpipe made. Any recommendations on a high flow cat for him?

 

Spd may sell the high flow cats separately id ping them

 

I can download the procedure from my Tech stream if you need

 

This is the cats SPD uses on their midpipes as the standard option. I got the part number right off of mine. Their more expensive option cats are made by Gesi. https://www.magnaflow.com/products/...mpliant-universal-catalytic-converter-99659hm

 

Funny you mention say this because I was planning on reaching out to see if you had a shop recommendation in the area.

 

For the valve body, probably AJ at AJ’s Yota’s in CP or Bearden would be the best two for that job.

 

Perfect. Exactly what he's looking for. Thank you.

 

ill tell you what, bobby
she scoots GOOD with 5.29s, holy hell!

 

Gears make all the difference in the world.

 

My American Racing high flow cats haven’t sploded yet, so whatever they use in the 3” variety seems good.

 

Yea they’re very straight through as well

 

So after bricking my ECU and swapping in another junkyard ECU (a few months ago), still getting an EVAP p0441. Replaced every evap related part but still getting the code while driving after 15mins. Thanks to JustDSM (whom was able to unbrick two of my ECUs) Im going to put one of those in now and see if the EVAP code goes away haha. Other than that, current tune is banging and ready to rip.

I guess the fall back option is to just tune out that code, it seems to reduce mpg though when evap isn’t working right.

 

The Tree's evap has had a fault as long as I can remember.

 

I still have the cat code, called SPD, they suggested replacing the O2 sensor on bank1 & are sending an O2 spacer free!

That's some great customer service!

 

Did you do a smoke test on the evap system? My code was the filler neck and evap canister but only way to really see it was smoking the system

 

I just smoke tested the BMW (finally running!!!) I had 2 tiny leaks, just needed to tighten 2 hose clamps. That thing is worth its weight in gold!

 

To deal with the 420 cat CEL, if it is the sensor I need to replace downstream right? The dropped valve was on piston 1 which is on bank 1 so I need to try replacing the sensor on the driver side?

 

Just remember tundra 5.7 drivers can be odd...

 

I haven’t yet and really should, I just figured it must be ECU related since it started immediately after putting in the different ECU, but could be an actual leak hahaha.

 

So although I am high, my premises are accurate?

 

You have Cats?

 

I'm a dog person, the Sequoia has SPD downpipes with highflow cats.

 

But seriously, I need to order O2s, don't want to get the wrong ones, especially considering the ones I have are under a year old. Downstream are what I need?

 

Ordered both for the left side. Problem solved, adios 229.

 

Don't know if it matters but the Gesi's are offered in two HP level ratings.

 

You better watch out @TurboKits looks like you have competition nipping at your heels....

and it already comes with Meth just not water/methanol

 

Only has like 46,000 horsepower, though...

 

But is there lag?

 

It's decorative.

 

It comes with decorative HP to boot. Dyno portion is after 9mins or later
