Removing valves in exhaust
 
I am considering doing a custom exhaust with 2 borla S mufflers with either an X pipe or H pipe. I am wondering if i should try to incorporate the valves into the custom exhaust or should i just leave them out. I was hoping somebody would know if there is any negative results if the valves are removed and if they are really necessary. Any help is greatly appreciated.

from evrywhere I have read it is bad to remove the valves, mainly kills your gas mileage from what I have seen

I'm not that worried about the gas mileage but I am mainly concerned about losing some low end power if I remove them. The H pipe is suppose to help with low end torque so they may cancel each other out if there is a power loss from removing them. I guess I'm am just better off incorporating them into the new exhaust.

low end was lost to I think. I would just incorporate them if you can, just to be safe

Yea. Thanks for the help.

Simple rule of thumb, if you are flashing the ECM to remove MDS then you can remove the valves. If you are leaving the MDS intact then fit the valves in the same location on the custom exhaust.

Eventually I'm going to disable MDS. I'm waiting for diablo to come out with the trinity for out cars. And hopefully you are able to disable it from that. I was talking to somebody who has a WK1 SRT8 and according to him he said that when he talked to diablo they were aiming right now for a September 14 release for the WK2 SRT's tune.

Leave them in, you can always tie them open as well.

no way that is true.....Ive heard from two sources that they may never be broken. ChryCo hired some company used by NASA and even Chrysler cant get into them. Dont know how true that is.....

X2 on breaking it

128 Bit I heeard. No one is cracking it. If Chryco doesnt release tuning by New Years Im going to be worried if it ever will happen before I lose interest. Im guessing there will be 1 licensed outfit that will produce pre programmed handheld tuners with Mopar labeling. Tunes will be very conservative, you can bet on that. We may find out what B&G is offering now is damn near what we will get in the end, performance wise. I bet there wont be 10-20 horse diff in actual HP output from the B&G offering and whatever gets released.
