Is there a company that makes a 4/4 collector that will bypass/replace the factory HTEV Exhaust Valve like found on the 929/954?I dont suppose you could just bolt the mid pipe directly to the header since you would loose factory mounting brackets and factory muffler location.

Its seems logical since the factory headers & mid pipe have the same OD as aftermarket full exhaust that it would be alot cheaper and the same power gain.

just pull the valve and plug it with a washer and nut.. thats how mine is

 

That would be the cheapest way to go.Are you talking about using the washer and nut as a block off plate?

 

yea, thats how we all do it

 

Got pic's?

 

Yep it was that HASS motorsport that used to do those eliminators. Not sure do they make them anymore.

 

nags is this what yours looks like?

 

basically.. cut that baffle **** off too
