How would the E55 sound if you just did 2.5" or 2.75" pipe from the Xpipe all the way to the back to the tips? better? worse?

Like a muscle car

uthustler

niiiiiiiiiiiiiiiiice, but too much for a 40 mile daily driver?

uthustler

where can Isee a pic of the underside exhaust of an E55?

blackbenzz

I would have to say yes. If you want a growl delete the resonator and secondary cats. If you want loud as hell at the push of a button get cutouts

Stock E55/E63s don't have x-pipe crossover. They have a H-pipe-type (not a true H-pipe) crossover before the secondary cats.

I have deleted my resonator and did the X-pipe mod after the H portion. What is back beyond my Xpipe where the resonator was?

uthustler

I did the Xpipe mod (resonator delete) and have a little more noise but not near what I was wanting, so wondering what to do next.

vegastrashed

Ah, I understand. You deleted the resonator and in it's place put a x-pipe. Now, you want to go straight pipes from the x-pipe thus deleting the two mufflers. It's going to be loud. I bet it's exactly what you're looking for. Give it a try and let us know.

I'm not too familiar with the 55K engine but I think you might lose some backpressure with the muffler delete, hence some loss of torque. Anyone, please correct me if I'm wrong.

uthustler

Hmmmm, may go do it tomorrow. Think it would take a good exhaust shop long? Like tell em to cut em off, straight pipe it, and let me drive it around, see if i like it and go back if i dont.

what is a good aftermarket muffler if that turns out too loud? I want a really throaty sound.

Should I cut the cats off? or will that throw codes?

Eisenmann race mufflers

Oh and make sure you post up a video with no mufflers, it will be LOUD

uthustler

cool, definately will.

what will two eisenmann race mufflers set me back?

uthustler

here is that pic I was talking about---

vegastrashed

I think you will like the sound of the mufflers delete. If not, then Eisenmann Race will set you back between $2K - $2,5K. I think you can find used ones for sale in the Classified forum every now and then.

uthustler

muffler delete wont be close to open headers will it? just checking, that is too much........

uthustler

only issue is, what kinda tips would I go to if i delete the mufflers?

vegastrashed

I'm pretty sure a muffler delete is not as loud as open headers.

As for what kind of tips, I'm not sure but I have heard that tips do have an impact on resonance, whether you'll have a lot or not.

If you want loud you could run my setup...Kleeman Headers,all 4 cats removed(2 Primary&2 Secondary), no resonators, Eisenmann Race

uthustler

gota vid clip? or sound clip?

did deleting your cats throw any codes?

baldmike73

what about the guy who did the exhaust dump? sounded mean when he wanted and then nice and quiet too. there is a set up that vettes use too. all done using actuators.


can't find the E55 who did this setup but sounded mean

uthustler

nice, got a link to some exhaust cutouts that would work well on the E55?

Here you go. These are what I use.

Once i get my car back I'll get a recording. I opted for the K2 program without the cats so I'm not throwing any codes.

LazyE55

Here's a sound clip right before i removed the remaining cats(Secondary). Basically it's the Kleeman headers, Primary Cats Removed, Secondary Cats Intact, Resonator Delete, and Eisenmann Race exhaust
