I've got an 07 S4R-T and I'm looking to do the Cat replacement pipe, to clean up the look of the bike, shed a couple lbs, and add some more sound...

but leave the stock slip-ons as is.. (not ready to core them just yet)

Has anyone tried this? how does it sound?

does removing the cat change flow enough to require ECU work?

is the Bike as smart as a car? will the 02 sensors notice the lack of Cat and throw a CEL (Check Engine Light) ?

any other general comments?


Thanks

We installed quite a few of the QD EXHAUST Mid-pipes .
They change the sound slightly. You don't need to change the mapping if you are only changing the mid pipe. It is a simple bolt-on.

Thanks Man

I just made an international order with you guys on Fri,

when I see the stuff arrive (and how long it takes etc)

then I'll be lookin forward to future business with you guys

So far Nick has been extremely helpful and comucantive

A+ to you guys


on a side note.. does your Pipe crossover? or is that a tab just to hold the 2 halves together?

Those are crossover tubes on the QD mid pipe.
