JMB Midpipes are now available with super high flow cats!

[JMB Justin]

Ive had some interest in adding high flow catalytic converters to my 3" mandrel bent midpipes. I now have the option to add super high flow catalytic converters that feature the same 200 cel per inch metallic substrates as much more expensive converters, for $290 to my mids. I have personally witnessed a 600HP viper lose less than 2HP with the addition of these over being catless, they are very high flow. I will update my website ASAP, until then feel free to give me a call if your interested.

The $290 is additional to the $375 midpipes. They will not be coated (they are stainless steel) due to the extreme temps that cats get. All 02 sensor bungs will still be installed in the proper locations too.
Thanks

That is awesome, but I am running out of $$ It is going on the list though!

 

[JMB Justin]

Typical gains from catless mids are 15-25WHP depending on your modifications. With these cats expect a very slight difference in HP gain over the catless versions, maybe 1-2HP less..

Your looking at $1215 plus shipping for the true 3" mids with the super high flow cats and a modified magnaflow catback (no 2.5" reducer, 3" all the way through). Let me know if your interested,

Please Justin quote me included shipment to Belgium. I do like big pipes ! :rock:

Can you advise me also that the exhaust won't need tuning ? Just bolt on and no issues with PCM, CEL,A/F mixture etc. ?? :dontknow: ( i'm in Belgium , so for tech help you can be as in a desert... )

I presume that this is for factory manifolds or shorties. Any plans for those who have long tubes? (Aside from an illustrious career in porno? )

I'll PM you, the rates were crazy! No tuning or changes are needed on a stock PCM truck and no check engine lights either.

Yes for factory manifolds or replacement style headers (bassanis, gibson). I dont plan on making them for the longtubes simply because there are so many different headers and configurations and a very small market for them.

Thanks
