Yes,right there brother.

Julio, that sounds great. Waiting for undercarriage pics.

On a semi-related note, I'd like to hear more vids of the gt pro double X pipe setup. I came across this videos a long time ago and the owner ended up being on this site. He really expressed how much it cleaned out the sound of the car compared to X/straight setup. It's so hard to tell over videos but I think this setup always sounded amazing. Is gt pro even still around?

GOT MY H PIPE DONE!!! Very satisfied with the sound

Also beat Julio to the undercarriage pictures


Enjoy~


1.5" tubing H pipe installed



Finished up by Adding some kind of rust prevention spray.

Guys is it me or is that pipe aluminized ? The OEM pipe are stainless steel. Why wouldn't the shop weld in stainless ? Just curious?

c63addix

its stainless steel dude, plus the car sounds so freakin nice now ! and car runs smooth as hell.

Higgs Boson

looks aluminized to me too.....

Julio Perez

I'm glad you like it c63addix,wait a couple of days,you will love it even more it gets better,and yes you did beat me to the pics,lol,good job and maybe from now on will see more c63s with the h-pipes,this set up is the best for our cars.

c63addix

hm I don't know then because when i was watching him cut the pipes to fit the gaps there were hella sparks. I could be wrong.. but I always thought only stainless steel will spark when you cut them.

SSSSE YA

I just want to thank you guys! I have been trolling for months here trying to figure out a set up that I like. I remember one forum member told me to install a H pipe to retain the AMG sound. I am going to have this done ASAP. I might have a problem having someone remove the secondary cats for me living out here in Kalifornia.

Once again thanks a million for being the Ginny pigs!

God Bless,

Last time I went to the muffler shop they said that I didn't have secondary cats... They were wrong right?

Aluminized

Stainless

To me, the rest of your exhaust looks stainless and the new pipe sections look aluminized.

Mikegpr03

Any metal will spark when you cut it. Thats not a determination on the pipe material used.

Make sure they used the right one dude. I'd hate to have a nice OEM stainless set up and then some "Hack" put cheap pipe on there trust me when I say this.

If you need to redo it for some reason make sure they use stainless (More $ but its the "Proper way"

c63addix

hm, the guy told me its stainless steel from the very first time I mod the exhaust. Now i'm a bit worried from your comments; if i got tricked or not how can I make sure its stainless or aluminum? With magnet?


EDIT: ok now i do suspect it's aluminized steel from reading about it a bit. Maybe I should go back to talk to the exhaust guy or maybe buy some high quality stainless steel pipes myself and tell him to weld them on =S

Does aluminized steel or stainless steel affect sound or anything? Or only the quality and durability? I have done many cuts to the exhaust lately and want to give it a break. Can aluminized steel last 6 months? I'll probably use them for 6 months instead of just wasting money trying straight/x/H pipes and now wanting to switch all over again. - -

^^doubt you'll be able to differentiate between aluminized and stainless steel, especially with such a short section of pipe. What you do want to verify is that the welds will remain intact between aluminized and stainless.

And sound clips please!

Sincity

Perhaps you can convince Mike @ MBH to make an H-pipe? Should be easier and cheaper to make than an X since they do make straight pipes to replace the secondaries. They already have the jig made for the straight and adding the small section should be simple for them.

farhadahmad

do u have to cut your cats off? or can can u just cut resonator and put straight pipe with that H 1.5 in the middle? does anyone have this setup with sound clip?

JulioPerez's vid on Page 2.. great example

And yes we removed our 2ndCats w/ straights, and resonators w/ straights. Then just weld a 1.5" tubing on resonator area to connect the banks.



Thanks for the advice, ill keep a look out.


And I'll make a vid soon when the weather gets better. The sound is truly sounding better each day And car is very smooth for some reason like the Xpipe or better.


I shoulda went 1" tubing for even crazier barks, but I was afraid there will be a lack of flow between both banks

Mischievous M

Sounds awesome man... Do you have a slight drone still in the car? Hope you enjoy the ride in good health mate. Make me wanna go back to stock system with H-pipe mods. Whilst I love my full IPE system with the valve control it sounds a lil too rude (in a good way) on the road but every jackass thinks you're initiating a race when the car down shift. :lol:

farhadahmad

what if i didnt want to cut my 2nd cats off? how would it sound? right now i have straight pipe on my resonator area. u think if i had an H it would sound good also even tho the 2nd cats are still on?

Guilty

Same question

farhadahmad

well ya and no? lol he said he cut off his 2nd cats . is that in the video with cut 2nd cats? or with just H pipe in resonator area? cuz he reply to it with a video link.

Guilty

He replaced 2nds cats with x pipe. I don't wanna do that. I just want to know how it will sound if I replaced the resonator by an H-Pipe

c63addix

Yes the video is no secondary cat and no resonator, just custom-made H in place of resonator.

I had your resonator delete set up long time ago, as my first mod. It sounded nice because it just sounded deeper and louder compare to stock, but sometimes too raspy.

So from my experience I think with that H pipe setup, your car will definitely sound cleaner and less rasp, but maybe a little bit quieter (still louder than stock though). Acceleration will be noticeably smoother.


I had no cat no resonator before with straight / straight setup.. it was way too raspy but loud. Now the H pipe just cut the rasp by half and sounds more tamed. It's only a little bit quieter and it sounds good.

c63addix

If you keep your cats, just H pipe your resonator then your car will definitely be louder and have the AMG bark. Without the resonator to baffle the sound, inside/outside will be noticeably louder.

I would suggest doing what me and Julio did, use 1.5" tubing for H pipe for more AMG bark


But I remember you mentioned you like the stock sound. You might not like the resonator removal because the sound will be much deeper than stock. You might think it sounds "cheap" (lol)


Found 2 video comparisons for ya:

STOCK-


RESONATOR DELETE-


Resonator just sounds a bit louder/deeper than stock
