CRV_33's Custom Magnaflow Exhaust

[CRV_33]

Finally pulled the trigger and went with a custom exhaust. I bought Magnaflow's Tru-X pipe # 10790 paired it up with a set of Magnaflow Round Competition series muffler # 10415. Talked it over with the exhaust shop and we decided to run 2.25" piping right after the 2nd set of cats. Since I didnt't want to run any resonators and the muffler shop placed the Magnaflow competition muffler in its place. The exhaust shop did a great job cutting into the bumper to accommodate the quad tips. I'm debating if I should go with a larger tip in the near future, what do you guys think?

Thanks to infinitedrift and Debonair for all your advice and patience. LOL

Sounds good, how is it on the highway? I used to run the same mufflers and X pipe on my Camaro but it was 3"cats and X, dropped to 2.5 for the axle back for sound and flow and it sounded good and less drone than the previous glass packs but still too much after they were broken in. I eventually went to a single 3.5" dumped and hidden but that looks funny when your bumper has a spot for the tips.

On another note, better do something about that rust underneath before its too late!

you got a sound clip on your Camaro?

When I left the shop the car seemed to drive weird and the exhaust wasn't ver consistent. I ended up unplugging the battery for 30 minutes to hopefully force the ECU to relearn. I've only put 30 miles on the car since then, but everyday the car seems to shift better and the exhaust note sounds stronger as the exhaust is breaking in.

Yeah I am slowly working on the rust issue, disappointed that the previous owner didn't really do anything to keep the road salt off to prevent corrosion at the rate it did. Sucks that I drive this car in MN and its going to be exposed to road salt.

That sounds very good!

You want the Magnaflow or the single pipe video? I'm sure I have both. The exhaust can change the tuning, when I went to the single pipe, the fuel ratio changed like two points or something. My tuner kept asking what else I changed because I had dyno'd it months before and it changed the maps bigtime and he couldn't believe that was it.

My car was from PA and it has some rust. Between that and my Land Cruiser I'm trying Rust bullet. It seems good so far but doesn't stick to smooth surfaces well. It likes rust better.

Any interior videos while cruising/gettin on it?

Funny you're talking about the car running weird after the exhaust mod. I had the exact same thing happen on my m37. Installed the Stillen exhaust and it seemed as if the car lost power on the lower rpm range. I ended up doing the ECU reset that @adeedpb sent you but that only alleviated the issue slightly. The car just ran like crap! Long story short, I ended up getting the Uprev tune last week and it completely resolved the issue. Car runs awesome now! U should look into getting it tuned. I was extremely hesitant at first but in the end it was Well Worth It!!!

All I have is dyno videos so you get a few seconds of "cruising" and then WOT so it's hard to get a feel of what it sounds like normally. The duals sounded meaner but I drive a lot of highway and I like it quiet, which the single pipe with the biggest 3.5" muffler Magnaflow makes sounds really quiet when idling and cruising but opens up with throttle and has a smoother performance sound.

Compared to another LS6 with similar mods except the other had true duals vs. my single, on the same dyno mine made about ten more horses but his made about ten more torque, so all things being equal, that's the difference an exhaust will make.

The first is with the Magnaflow duals, second is single pipe and the giant SUV Magnaflow.

I tried this several times on my M56x , and I can't seem to get past step#5 where the check engine light flashes. Someone mentioned that disconnecting the battery for an extended length of time will do the same thing...since I just had my timing chain recall job done (battery was unplugged for almost a week) I wonder if that reset the ECU?

I have a hard time getting the timing right when I just count the seconds but I copy the video as he is doing it and it works great. His counting is a little different that I would count and seems to give an extra second or two here and there.

Thanks! Yeah I will try i out this weekend

Haha not yet, trying to getting a consistent acceleration down first. If i don't have anyone in front of me during the acceleration process the car sounds smooth.

If i am accelerating from a stop behind someone going at a snail pace, seems like 2nd and 3rd gear doesn't really got much pull it almost sounds like its stuttering exhaust note, but 4th gear the exhaust note sounds normal.

I'm going to hold off on doing a tune until I at least get the R2C intake, which hopefully comes out soon. I had a friend with a supercharged G37x that had his car tuned by a local shop in my state, when he got his car back his transmission was all messed up. I'm hesitant to have that shop work on my car.

Haha wow the first video sounded really badass!

Never heard of Rust Bullet, I am going to look into that.

Dude I have tried at least a dozen times or so but still can't get the service engine light to blink. I've counted the seconds like the video, used a wrist watch with a second hand, counted a little slower, a little faster, etc. No luck.

Since I had the battery disconnected for almost a week, due to the recent timing chain recall work I had done, I am going to guess that the ECU was reset by default, plus I think that they reflash it anyway.

[DoN_BLaZe34]

CRV, the exhaust sounds really good.

Like Ilya, I'd also be interested in hearing it from inside the car/cruising around. I fear it may be a little loud for my taste. Any drone at all?

Hopefully I'll have time soon to try this out.

When accelerating the car is really loud especially when you get on it. But once you get to a cruising speed its completely quiet like stock. This is was a crappy video I took right after I installed the exhaust. First 14 seconds of the video is accelerating from a stop and entered the on-ramp for a freeway around the 21 second mark. I absolutely hate exhaust drone and this car doesn't really have much of it because our car coasts below 2,000 rpm's

[Ilya]

That doesn't sound too bad...not much different than my MXP on my M35 which I liked, a lot.

[CRV_33]

Here is another clip taken yesterday with a shotgun mic mounted on the rear bumper. There is a rev match clip when the car downshifts at the 1:07 mark.

[Ilya]

That rev match was nice hah

[CRV_33]

That rev match was nice hah

haha i know! The first time it ever happened it completely caught me by surprise, I thought I broke the car. LOL

[MY2J]

bump for pics re-upload? would like to see how quad tips look on our vehicles

Hey man nice setup. I just have one quick question. The quad tips that used are they staggered or flush even with each other and also where did you purchase them from? I'm looking to have my exhaust done in the next month. Thanks

They were non-staggered 3" tips. Honestly I bought them on ebay and the description i used was "PAIR STAINLESS STEEL UNIVERSAL DUAL EXHAUST TIPS 3". I just did a search and I cant find them for sale anymore. The sellers name is: upswautoparts

[DRM56]

Thanks man...i found some 4 inch quad tips so I may just run them with my magnaflow mufflers.

The ECU reset doesn't work on my car either. I've tried many times. It never has an effect. The infiniti service guys laugh when i tell them about it.

I DID have infiniti do this on my older G35 coupe years ago. But on my M56, nada. It does nothing.

ECU reset procedure works great on my 2011 M56S. When I reset the ECU the car turns into a rocket and makes the DBW throttle super responsive for a while.

Honestly I used to have problems with my ECU becoming sluggish but i feel like my car has stopped "learning". I know that's impossible to turn that aspect off, I've asked Infiniti several times. But currently i don't know if I even need to do the reset. But I might try it again just to see if it finally works. Won't hurt to try.
