Default LM1 exhaust clamp

i know the best way is to use the O2 bung in the header, but have many of you used this with much luck ?

LOL Innovate. NOTHING I ever bought from them worked worth a ****.
Theres my opinion. $600+ in equipment, shipping it back and fourth for repair all sold on ebay for $120. Thats 8 months after initial purchase.

Clearly experiences will differ.
I have used my LM-1 for years with positive results. This winter I picked up the exhaust clamp. My tuners have always used their clamp with their software. The Innovative clamp is just that, a clamp which you thread your O2 sensor into, so it should be just as accurate.

It's just a keeper widget, I use a piece of coat hanger
wire myself. If you want to look like a pro then you may
go for the shiny store-bought'n but there's plenty of ways
to cobble up something just as functional.

thats what I thought jimmy.

Most C5 exhausts bend within a couple inches of the opening, and im wondering what to use for my widget.

Im wondering If i could use some kind of flexible tubing and I can add the bund for the sensor

I've used this part with decent results. With any tailpipe clamp, and idle or part throttle data is basically worthless. The WOT stuff once you exhaust the oxygen out of the cats should be very close to the second o2 bung location.

I have had one for quite a while , works great on some exhausts and others with big exhaust tips that step up tend to suffer from reversion and throw off the readings at idle and low rpm.

at criuse and WOT it works fine giving the same readings as a second unit in a front o2 bung without cats.
