Re: No Mufflers... (corvette90)
Unless you have a federal requirement for mufflers, just replace the sodding things with straight pipes. I took my '86 to a muffler shop and the bent up some pipes and just eliminated the mufflers. I also put a high performance catalytic converter on it, which increased the HP somewhat, but reduced the backpressure to the point that I always get a code for the EGR. There is not enough backpressure for the EGR to work. But as long as I know what the code is I don't care.

ah yes, i wan´t to let in stock cats, no gutting..
nice loud..but not too loud..
loudness is no real problem here, since the cops don´t know, how these cars sound-there aren´t many of them.
but i want to pass emission..
so..
ok...thanks again..

Re: (91Yellow1)
...i asked a dealer, he said, no codes, when i drive without mufflers...
Where is the backpressure measured? I thought, the EGR only allows to return a various amont of exhaust gases...
Is there a pressure control for the exhaust gases in the valve?
Can anybody explain me, please??
Thanks
