R36 Deleting the exhaust drone accomplished!

[dannyjak]

Is the raspiness coming from the hi flow cat? given your second video, it appears to be the case.
Im trying to figure out whether you can get the raspiness without changes the cats

[Mr R36]

Correct, the second video is cat without suitcase and no j pipe just straight pipe.

And yes the cats alone did achieve the rasp but didnt cancel out the drone. The j pipe is my effort to cancel out the drone from the middle resonator so a j pipe or helmholtz resonator in replacement of the suitcase might be good enough for some of you.

Heres a video of cat + j pipe on cruise and under heavy throttle

I've noticed some of you are keen to experiment the whole lot of what i have tried minus the high flow cats: can i ask what is influencing this choice? If it's a cost factor it's worth mentioning that where I went (in Melbourne obviously) they did the cats and said they can install a helmholtz resonator for free if i wanted. They ended up customising a j pipe for me in the end as i was a repeat customer. If you did the other way around (install helmholtz resonator) and decided you and cats i don't think they will give that away for free...does this make sense?

[dannyjak]

Cat cost is the majority of the reason for me. I dont feel like its not an important replacement unless the raspiness only comes from the cats. Happy to just go to an exhaust shop to get them to delete the suitcase, and add some J-pipes

Once again, helpful videos Mr R36!
I'm the same as Danny regarding cost of the cats as the inhibiting factor. Maybe I should take you up on the group buy you suggested earlier

Yup, lets get some pics and measurements!

[Mr R36]

I've learned how to post videos but not pics yet....umm how do i do that? More vids now with current setup with j pipe and deleted hotdog. As you can tell the combination made a completely different animal

Awesome job there Mr R36! I am also a customer of Trevor and he also suggested me to change the hi-flow cat. I am wondering if I can meet you sometime so I can listen to the exhaust in person?

[Mr R36]

It's much different in person. Maybe we can get a discount on remus if we both buy down the track

Yeah sure my just give me a call 0401864193
