R36 exhaust - "suitcase" delete review

[ING36R]

yeah i think that is normal for about a week for the correct sound.

for those that are reading the above comment re drone, keep in mind that i am referring to the 3.6L V6 engine in my car, i would assume that team_v has a 4 cyl engine?



let's not fool ourselves, 10kg isn't going to do anything. that's the weight of my baby seat, or a big lunch at all-you-can-eat!

no problems mate, my aim to is give some more objective evidence of the result to help others out, i would have liked a review like this before i did it.

my other mods are only EVOMS intake (also highly recommended - perhaps i should do another review) and Kufatec E-MFA module (for digital speedo in the early "red" instrument cluster).

I can't justify the cash for the small gain from an ECU remap. i did have a sprint booster on my previous car (CLK500) and it made a big difference, i might consider it, did you get it front that website? how much did it cost you?

i would argue that 1-3 hp on a dyno is within the normal error margin.
on a non-turbo car this kind of mod is never goign to add power.
safe to at least say that its not going to lose power and be happy at that!

Hi Warren,

Sorry hadnt got back to you earlier.

Been thinking about Gruppe-M intake, but want to minimise mods to engine as i think the Sprint booster is enough and i have BMC pan filter to help breathe better.

I spoke with Thomas owner of Ramspeed and suggested this for NA, gteed money back if not happy with it and was a cheaper at $590 delivered.

Can get cheaper from US website, but not sure about warranty as not supplied locally. No recourse???

Was going to get John from BM autowerx to install it, but did it myself as you know its pretty straight forward. Guy at work has a R36 Wagon same as mine and he did ECU remap. I drove it cant tell the difference in power and that was $1300.

People who have ECU remap and gain 17kw extra say the fuel consumption improved aswell, can see how?

You going to Winton on Monday?

sorry i couldn't understand what you were saying at the start of the post, so you got the Gruppe-M? or were you referring to the sprint booster?

interesting what you say about your mate's wagon driving the same with the remap done as most say they feel a difference, but then again most won't admit that there isn't too much difference after dropping over 1k, that's the nature of the internet and has to be factored in when reading subjective posts i think

what's happening at winton? i won't be at a track meet though, have a young baby to look after.

Sorry, I was referring to the Sprint booster which i installed myself and had considered a Gruppe-M intake but didnt want to make too much engine mods.

I thought based on what Ramspeed told me about saying the sprint booster is better bang for buck over remap, that clearly was better option and can switch it off sold me on it. Plus, he gtee if not happy he would refund so.....couldnt go wrong.

Sprintbooster works well as predominantly wifes car, so she drive auto and doesnt impact on the way she likes to drive.

I was thinking of checking out the VW track day tomorrow @ Winton, but too far to go to just watch.

If you can, join us at the next Melbourne drive day on Sun 1st July as it seems to be alot of Golf/Polo owners, but not many R36's?

Thought I would post a bit of an update…

Its been a while since I have done the suitcase delete and after a birthday (hence some extra cash) I decided to do this properly and install some aftermarket mufflers. The suitcase delete was always a cheap option and in an ideal world I was always wanting to go aftermarket.

Searched the net for a few …
The best seemed to be the Innotech IPE exhaust but it is a very expensive option. Supersprint was also too expensive.

Had a few places quote me on different custom things to do to the car, varying widely in their approach. One place suggested that I go 3” pipe from the cats back to the bifurcation, then into twin 2.5” piping with only hot dogs on the rear. Obviously this place was unaware of the drone issues that we can get with this engine and not listening to what I wanted from the car.

Finally settled on the plan from a local place where I have been before (they did some work on a previous merc that I had). I actually think this is the same place that ING36R went to as they talked about a wagon they had done where they removed the suitcase and ended up re-installing it (due to drone) and going with twin Remus mufflers on the rear. Is this your wagon?

My budget was limited so I couldn’t afford the Remus option. My requirements were for slightly louder than current but still no drone. I know the car can get boomy just above 2500rpm (as per stock setup) but I wanted to ensure that there was no drone.

After a bit of testing they confirmed that the current rear mufflers were already a straight through design and could pass a wire through them easily. So the plan was to go for a straight through muffler but with less packing. They also suggested putting the centre muffler back as it would otherwise be too loud and also probably drone with the aftermarket rear mufflers.

They warned against lukey, magnaflow, xforce and a few other aftermarket ones (previous bad experiences). Apparently most of these are nothing but a straight through pipe with not much actual packing. There wasn’t anything in stainless steel in my budget that was actually worth having.

Their advice was to re-install the suitcase and replace the rear mufflers with straight-though mild steel mufflers. They suggested I use the OEM middle/centre mufflers from a commodore which are solid, good quality, with lots of packing, but with little-no restriction. I liked the idea as they are a muffler designed to work from the factory rather than some cheap crap from china and who knows what would be inside. I also asked for larger tips as I wanted something that looked the business. I went for long 4” tips (similar to OEM but bigger).

The result? Well the sound character is very similar to before but the sound is slightly louder at all RPM particularly at idle. Its actually slightly less “boomy” at 2500rpm than with the suitcase, more like stock, and definitely does not drone. Overall very happy with the result and this is really a nice upgrade for the price. And worth it for the nice 4" tips.

From what this exhaust guy has been saying about wagon drone it sounds like there has either been exhaust changes at the MY10 upgrade, or the wagon just has a greater propensity to drone for whatever reason (slightly longer exhaust or differences in sound deadening?).

Pics:





I have another pic of both tips from the rear but have to download it from my phone again.

Hope this helps those after an upgrade.

I can divulge the name of the exhaust shop if requested.

Cheers.

Now the search begins for a nice carbon diffuser (aka C63 style) to go with the tips.
Not sure if one exists though...

Hey Waz,

The rear shot looks awesome mate, and thanks for the write up about your new exhaust. It's something I've been thinking of since I got my R36 last week! Are you able to record the sound from idle to mid RPM to high RPM for us R36 owners considering something like this?

Thanks Waz
Cheers
Chris

sorry mate but i don't have the equipment, time, or patience to record sounds at different RPM

perhaps chat to the guys at Muffler Man on Malvern rd, Prahran for some advice

For anyone who is interested, i have just had both rear mufflers replaced with magnifiers and had the suitcase muffler removed. Little drone, very good exhaust note - a definite recommendation.

Magnifiers?

More drone than Oem?
