i had a shop remove the resnoters it does not sound much louder
should i remove the cats too

tbal

Search is your friend!

Resonators dont really do much... Most people remove the secondary cats as well. If you want more louder, remove the primary cats too!

black05scamg

will i lose power if i remove the cats

tbal

No probably gain power! But removing primary cats will trigger the Check engine light.

what tbal said is exactly right. My old setup was removal of resonator and secondary cats with an x pipe where the cats use to be. Noticeably louder and refined sound with no check engine lights either.

black05scamg

anybody have pics where the x pipe goes

tbal

I suggest putting it where you took the resonator out from. (out back) Seems like that resonator also crosses over (xpipe)... Must be a reason why the amg techs decided to put it there...

I definitely lost major torque down low when I removed the resonator with straight pipes. I should get it back though when I do the long tube header system and a tune.

tbal

Really? I didnt feel any difference, typically xpipe does lose bit low end, but gain mid-top end... Good thing maybe lol, god damn 1st gears useless haha (too much tq)

mikey33

Lol still got a lil torque left . Still I know I lost some cause the takeoff is not as violent.

I highly doubt you can feel a difference in power from removing the resonator..

To the op, I would put an x-pipe in place of the secondaries if you chose to remove those too..

E55Dimon

Wait, removing JUST the resonator will make you lose torque??

Viet_Amg408

no, removing Secondary Cat will ...

tbal

I didn't feel any difference...?

AKnight55

You wont.. "Take off is not as violent" is BS.. No chance you will ever notice it from a resonator delete.. There is so much wheel spin from a dig that its not even close to noticeable..

My advice is to go with a resonator and secondary cat delete with an x-pipe in place of the secondaries and you will have a nice sounding beast..

tbal

Does placing the xpipe in different places result in different gains/loss?

I'm sure it's been discussed lol

AKnight55

Not sure.. But I've heard placement might have a factor in drone.. Placing the x-pipe in place of the secondaries would be your best bet..

mikey33

Actually my car did lose torque and I CAN notice it!!!

AKnight55

You lost what? 5 ft lbs on a 516 ft lbs car.. You must have a special gift

black05scamg

lol 5 lbs lmaoo it does sound a Little deeper thats for sure but i do feel a little loss and it not from a dig its more mid range rpm maybe its all in my head lol
if so ill put back the res

guysandiego

I did this too -- but i have a small H pipe where the cats were at and I have a 2 3/4inch x-pipe where the resonator was at... no drone - no problems --

tbal

h pipe and xpipe?

mikey33

You must be retarded telling me something about my car when you never been in it before.

guysandiego

yeah - i have both ... its no big deal. I think the stock system has a slight H around the cats and possibly a merger at the resonator.... So, I just kept that same design but eliminated the restrictions 'cats and resonator'.

AKnight55

Dont need to have been in it buddy boy..
