Hey guys,


What would make the exhaust louder without the resonator? two straight pipes or an X pipe???

I'd think the straight pipes, since with the X pipe you probably get some noise cancelation from the pulses. I don't see why people want these cars louder, for me the car is plenty loud enough as it is.

I think the quantity of sound would be about the same. The quality is a little different though. Do a search theres a thread with sound clips comparing straight vs x pipe.

x-pipes will quiet it down a bit more than an H-pipe or straight through...

I removed my resonator and installed straight pipes in place. Definitely louder and sounds much better(to me). At first i thought it may be too loud but now its perfect.

^^ awesome thanks for the feedback guys! Starting with the resonator then after that ill decide if sport mufflers are needed or not haha

How about power loss with a straight pipe since it will lose back pressure? Is a x-pipe advised over the pipes instead? Have you taken that into consideration?

When i did the X pipe on my 07 E63 I noticed some low end power loss. I tuned it soon after and it felt great again. Not sure if it would have felt better with the tune and not removing the resonator but it sure sounded great. With my current M157 resonator delete and straight pipe I noticed zero power loss, just awesome sound and plenty of power. I plan to get a Renntech tune just a little hesitant wiith the warranty and all. I'd say remove the resonator and get a tune.

The M157 is the 5.5 BiTurbo Correct? I was considering removing the resos next year but no tune as my car is brand new only a few weeks old and I'd like to retain my warranty.

So on the 5.5L BiTurbo you noticed no power loss with a straight pipe in place of the resos or did you go x-pipe?

Thanks

vcci

Correct the M157 is the biturbo. I believe your 2016 is also the M157. I went with straight pipes and noticed ZERO power loss. Love the sound.

Very interesting, I will take it into consideration next year I like the way the car sounds for the time being, but things always change.

Thank you I appreciate your feedback.

vcci

I'm willing to bet once you get it done you will wish you did it sooner.

Mine only lasted about 3 weeks before it came off

vcci

you have a lot more patience than me

nstanford99

ahhaah my car is weistec tuned! So i shouldnt see a power loss hopefully! VCCI they are in your neck of the woods man you should check them out! My car is a complete beast thanks to them! PM me for details if youd like

nstanford99

alright so update, the shop said for the same amount of money they could leave in the resonator and do a muffler delete and add straight pipe. would that give me some good sound??? or would it be a cheaper sound?? if you know what i mean.

thanks for the input

vcci

and why not remove the resonator?

nstanford99

not sure, they said it may sound better with it in and the mufflers out???

vcci

Do they have an E63 with removed mufflers and res in place? So far every thread I read from people who have removed their res have all had positive feedback including myself. I would trust the many E63 owners over someone saying it "may" sounds better but I wouldn't mind you trying and reporting back.

sc98

I would think taking out the mufflers would be significantly louder than just resonator off.

vcci

I agree but i don't necessarily believe it will sound better.

nstanford99

yeah so if i went with taking out resonator and the mufflers would that have a nice awesome sound to it?? or would it sound cheap and obnoxious??

vcci

Remove the resonator and see how you like it, if its not enough for you then remove the mufflers. Personally i think it sound awesome as do most who do this mod.

vcci

or just remove the mufflers so i can hear what it sounds like.

sc98

There's a clip posted by I think TTA850 of his Cardinal red with straight pipes replacing both the res and mufflers.

Sounds bad *** but I wonder if it'd be too loud for me personally. I have res delete + cattted DPs which I feel is perfect for me.
