Went ahead and started the modding process today, figured id show off a few pics.














The car really sounds nice now, I cant believe what I was missing out on, 120 bucks well spent

jturkel

glad you like it! what size piping did you use to replace the res and 2ndary cats?

aho

I think he used 2.25 for the sec cats then 2.75 from there

C_DirtyTwo

see I have a resonator delete, but I am looking for a more beefy sound. I want to delete my cats but Im not sure how much of a difference that will make...and I also cant pass CA smog without cats....My next option might be to just take off the muffler any suggestions?

RLx02

Do they do a visual check for cats? Because (according to a smog cert. shop owner in SF) healthy cars will pass smog tests even without cats.

C_DirtyTwo

oh really? I doubt they do a visual especially on a Benz....Im curious to find out

Great shots aho! These will most certainly make it to the "Tech Thread". I'm sure there's quite a few members who'd like to know what the factory setup looks like in detail.

Who cares if they do? The car still has 2, that twice as many as they're used to seeing. Like the guy performing the inspection knows the car had 4 to begin with. As long as the computer says it's doing fine there's likely to be no problem whatsoever.

I think vomit had a thread going a while ago that his, or a friend's of his car passed the Cali smog test without secondary cats. It will be louder, but the thing that started to annoy me was the cruising speed drone

C_DirtyTwo

Well in that case, I might just have to delete my cats in the next few weeks. And as far as the drone goes, Im 20 years old I want my car to be very low, very loud, and very fast and look kinda cool too

Sell the AMG now and buy and evo
GL on the swap-I'm still trying to find a shop to weld man-or try and butcher it myself some weekend

I had my resonator and secondary cats removed hoping for a deeper tone. Instead mine sounds raspy and high-pitched; fine for a Honda but not for a Merc. Now I am looking for a decent resonator to put back in the car to attenuate the high frequencies and just leave the rumble.

jturkel

well thats odd. never heard that complaint ever from anyone ever doing a resonator delete. high-pitched and stuff. huh...that is seriously weird. what size piping did you use to replace the secondary cats and resonator? too small maybe?

MountainStone

Resonator was replaced with 3" stainless and cats were replaced with 2.5" (I think - they look identical to the original pipes where they are welded together). Car is a good bit louder and I don't care for it. The sound is not throaty but nasally; it sounds way too Fast and Furious for my tastes (but I am 38 and long past my 'look at me' stage). I deleted the resonator first and the sound was not bad, but when I deleted the cats it became unsatisfactory for me. I think one or the other would have been the way to go.

jturkel

hmm.....well i know a while ago a member named AirFrced put an Aero resonator on his car. if you want to put something back on, i suppose that is an option.

SilverBulletAMG

First I've ever heard of that complaint. Please get some sound clips. Have you head to clips of others with res/rear cats deleted? Does your sound different somehow? I don't get it...

MountainStone

I'll get some clips. I haven't heard anybody else's clips. Maybe it's just my own sensibilities; sound is a subjective thing after all...

MountainStone

Aero makes some very nice stuff. I had an AeroTurbine muffler on my Tundra and it sounded so awesome I got comments routinely. The muffler itself was polished stainless and gorgeous to behold. I'll have to see if I can track down one of their resonators...

SilverBulletAMG

True, sound is subjective as to what sounds good or bad. However, up till now it's been unanimous that removing the rear cats and resonator gives a "deeper" sound. That is not really a subjective statement and more a matter of fact.
There is no reason you should have a higher pitched sound, unless you can hear your SC through the exhaust or something. Have you checked out all the welds? From the sounds of it, adding a resonator won't make you happy. You will want to look at different mufflers.

C32 AMG////

Hey guys I have a 2002 c32 AMG and currently I took the stock muffler off and replaced it with a flowmaster. It sounds good on the outside but too much drone inside around 2500 RPM. I was doing some Research And was thinking about doing a secondary cat and resonator delete with the stock muffler. I have heard the video clips on YouTube and I love the sound with those two things deleted and putting the stock muffler back on. My only concern is how loud is the drone going to be inside the vehicle when crushing on streets or highway with the secondary cats and the resonator deleted?. When I bought the car, it came with the resonator deleted and the drone was not bad,you could barely hear it. Also when the secondary cats are deleted, should I replace them with straight pipes or a x-pipe going to a straight pipe where the resonator would have been. Any suggestions? Thanks
