I have a Remus exhaust which is great, but I'm also contemplating an x pipe. Anyone know if it is even possible on a 320? Most discussions I see concern a v8, so I don't even know whether the piping set up on the 320 allows for it. Of course, any soundclips/descriptions are recommended. Thoughts?

Thanks.

And by recommended I mean appreciated...

Im new owner of an e class as well. If you take a look under your car and locate your cat. If you see two pipes coming out from it then you can install an x-pipe but if you only see one, then I dont think you can. Sorry for not using correct termonology . Hopefully one of the senior members can confirm. Hope this helps.....

the v8 engine you don't gain much of anything(power or nicer balanced exhaust note)
by installing an X-pipe on the M112 engine.
You might find a nicer note(not buzzy remus like) by using an H-pipe.

hey man ... ditto OhLord .... or just delete the rear cats for less .... look here for some pics, etc... https://mbworld.org/forums/e-class-w...ling-w210.html ... good luck!

ohlord, thanks for the insight - I've found your posts to be very helpful in the past. So you really don't think I'll get any gain from this? FWIW, I did notice a difference post-Remus install, with freer revving and it seems like a tiny bit of power on the top end. I thought either an x or h would add just a bit more power on the top end. For purposes of power, isn't an x pipe better? Do you buy into the concept of a "stamped" pipe being inferior and causing a buzzing sound v. the custom made Exhaust Depot type?

Also, from what I understand an H and X will both add some top end power, but the H might help with torque, at the tradeoff of adding less top end HP than the X. Is this right as a general matter (notwithstanding what you said about not seeing much of anything on the v6).

Kbad -- thanks for the info, I apprec the link.

Thanks!

hey Vokaertfan.... it really has to do with resonance....basically, it is how the exhaust is tuned and the 'stock' placement of the X will not allow for the gains you would appreciate... however an H will allow for some gains, again not too substantial, mainly because of the stock rear cats and the resonator before the muffler.... notwithstanding, you are free to spend the cash and have an expert exhaust shop tune your exhaust with an X or an H, but as OhLord depicted, it may not be worth it on your particular model unless you get the whole exhaust system reworked, but then the v6 combined with the weight of the car just doesn't have what the v8 has.....

....another thing to look into would be to open up the intake.... the v6 and v8 share some common components, however, for some idiotic reason, mb decided to short-change the v6ers! you can modify your intake from the throttle body out.... that is, to replace the 68mm v6 tb with that of the 74mm v8 (plug'n'play) including all of the tubing (from there to the air box - on the v6 it's all 2.5" with other restrictions along the way, whereas on the v8 it's 3" and most restrictions have been removed).... the added air volume will give you back some of the lower/upper end gains which the stock intake is robbing you of, combined with your upgraded exhaust, you may not need to modify your exhaust system to be happier, for now!... good luck, mate!

Woa...kbad, I had no idea about this intake stuff! So a 430 or 55 throttle body will drop into the 320? What other parts would I need? I'm not too mechanically inclined, so I would have to have a shop do this unless it is pretty simple...is it? Thanks for the info! I'm having fun trying to get little gains out of this car...

low end torque. You will never use high end hp on the street so that is a moot point.
If you don't like the common sound of the Remus.
Also note TB out stated above. The throttle body itself from a V8 m113 engine won't fit. The tubes might but you won't gain.
Rim the car tastefully((18's) drop it properly(camber adjusters and all)
Reset the trans to factory default(zoom zoom)
and enjoy it.
Little HP gains on the M112 are pricey,bigger gains are more pricieer
