CVF catted downpipe

[ST_Ranger]

Hey folks - since the thread is active just a head's up that our best sale of the year is active! 10% off plus no taxes added (we eat the cost) and free shipping to the lower 48 on any CVF-branded products. Feel free to give me a shout via PM if you have any questions as well!

I have spoken to many people in my FB groups and forums. It seems as the the coupler(s) that come with the catted DP do not fit snugly and leak. I have personally tried to adjust it several times with no luck. To be clear, it is the DP to Coupler not the coupler to exhaust. That end fits snugly with no leaks.
Any suggestions?

Have you looked at trying another brand of coupler?

There's no coupler in the downpipe kit, but there's the metal adapter from the downpipe to the exhaust - is that what you mean?

If so shoot us an email with an order number and we'll get you a replacement that we test in-house.

We haven't had anyone contact about this but things can happen with the batches, so we'll get it looked at/rectified immediately. Feel free to message me directly at [email protected]

Adapter/coupler/connector. lol
I have sent a message via "contact us" on the website.

It leaks on all 4 splits in the adaptor fully seated over the exhaust. I believe the ID is slightly larger than the OD of the DP.

I dropped you a PM - may be a batch issue we've since fixed, just want to make sure we're on the same page!

We have these in stock if I'm not mistaken, but I'm 99% sure it was a batch of adapters that were a bit more flared out and we resolved. If it's that we can quickly just shoot out another.

Yes - it was a few adapters in one batch. We resolved it a while back and replaced the leaking flanges.

So I eneded up paying my mechanic which I hate myself for but even they had a really hard time with it. Took them 3hrs. And cost me $300. Mechanic said 02 sensors were the worst part. First impressions, wow. What a difference. Power is on tap. I've done turbo back with mbrp single side exit and exhaust is definitely louder. Cold start is not gonna be fun for the neighbour's in the winter. There is a slight bit more drone in the cabin in throughout the gears but smooths out you get higher up. Torrie adjusted my 91 tune and this thing is a beast. I've also done mishimoto charge pipes and BOV plumback. This thing brings so much joy to my life now.

Before your tune changed did you notice any of this?
…I did MBRP single side and noticed a loss of power down low, some slight hesitation from a stop, and the tranny shifting much earlier now. It screams when I put my foot in it, but if I’m easy it will be in 3rd gear before I’ve complete a turn from a stop ligh. Then it’s bogging on accelerating from there. I have not emailed Torrie yet.

Some of that sounds like DPFE sensor issues. May be time for a replacement.

@Superdannyboy - My friend uses the smallest insert. But to clarify this is only needed for catless downpipes.

Your downpipe is catted so should pass inspection as I would think the catted downpipe doesnt cause a CEL. Also, I’ve never seen an inspection failed for the presence of an aftermarket cat.

Let me ask you, what defouler did he use. Did it look like this??

Correct!

 

[tygr2007]

Correct!

Haha perfect! Just put this in today and used the smallest thing like you said. No more CEL!
