Exhaust & Tune adjustment?

[mackthehack]

If I put my muffler back on to my 5" down pipe back system.

Would I have to make adjustments with my tunes to accomodate for the little back pressure produced by the muffler?

I know my tunes are set up for being straight piped. Its a Magnaflow system.

not sure about the tuning, but I know my egt's went way up after putting my stock muffler back on and it seems a little more laggy but it may be my imagination

Yeah... Definitely not putting the stock one back on. It will be the Magnaflow 5" muffler.

Its a flow thru.....shouldnt need anything done to tune.

I just bought a Magnaflow 5" on my LMM. Not sure if im digging the drone going highway speed. Did the muffler help with drone at all?

Can't answer for 5" since mine was always with out a muffler, but when it had 4" the drone was non existent when it had a muffler in it.... take it out for a delete pipe and it got pretty loud.

I haven't been able to reinstall my muffler yet.

With the 5" the drone is more prominent.
