New Exhaust System

Well that was quick

 

Well, I don't actually have them installed lol they've been sitting in my garage since I bought the system a few years ago

 

I have just one 200 cell ARH per side and I definitely get CELs if the o2 sensors are placed in the normal spots. So running sequential 200s or a 400 is likely way less headaches. The 200s also don’t remove all the gas smell either, not terrible but noticeable on a cold start if you’re behind the vehicle.

 

I had the tuner delete the CEL, but again, catless here. I love the gas smell but I got used to driving a 78 big block.

 

Yeah exactly, I think I’ll tune out the CELs too and put the o2s back in the normal spots as well.

 

Im still running the URD sims with the stock location of the O2's. Could try the j shape anti-foulers.

 

How do the 2 systems compare in terms of sound/performance? I’m in California unfortunately so I’m assuming I can only get the non-catted version?

 

Sound clips on their YouTube. Stock downpipes with their cat back https://youtu.be/GkKvXXoTi9A?si=GVgRnaZ4tWPPhtGN

 

Yep, cat-back system is all you get

 

So many choices out there for exhaust. Considering I’m in California and I can only get the non-catted version, what sets this one apart from the multitude of other exhausts out there? Dirty Deeds, Borla, Flowmaster, Magnaflow, etc…

 

Easy fix send to a friend not in California.. then ship to you. I did this for a buddy recently lol

 

Equal length, x pipe, dual 3”, high clearance, 304 stainless.

 

No smog/emission test in CA?

 

They don’t know the difference of having 2 cats or 4. No cel lights and it still passes the obd test

 

WA recently stopped smog checks which I find hilarious. I used to have to rev my manual 1994 mustang in the check facility, super weird. I guess technically you’re supposed to have factory exhaust equipment but not sure how it would ever come up unless pulled over for loud exhaust or something, I would just point at the TRD on my rims and be like “I have the OEM Toyota TRD exhaust! Was an option back when Toyota sold gas cars. Can you believe it?”.

Eventually when all other makes of trucks are in the junk yard the Tesla NPC cars will complain we’re the only exhaust you can hear .

 

Way back in the day with my 1st gen Tundra, I put on a Bassani exhaust that eliminated the 3rd cat. It passed smog but after a couple years went by, they started doing visual inspections and it no longer passed. I had to have it modified to put the 3rd cat back on.

 

Lots of buddies in SoCal and I was from there never had an issue. Let’s be honest California is home to some of the most modified cars around lol. My buddy cut his secondaries off last month and smogged it

TX only has emissions testing in the larger counties as of 2025. That being said, I've had a passing inspection every year solely because the inspector I go to has yet to do a visual on my undercarriage...

 

Visually I have 2 cats per side...just saying.

 

I have a dd dual exhaust would it be a huge diff in performance/mpg changing to the spd exhaust? I would be interested in the cat back one?

 

So this will not fit a 2013? It only shows fitment for 14-21 trucks. I thought the exhaust was the same from 07 on.

 

Actually 07-09 are different. 2010-2021 are the same and it should fit.

 

Came in on Friday...

 

Nice. Mine comes in today but my truck is in the body shop until probably end of the week

 

That’s the worst when fun parts come and trucks not around.

 

Woo!
