Here is my cheap o way of fixing the problem with my mrts v2

I bought some of that egg crate foam from walmart and tossed it in the trunk. I ended up buying another bag of it and doubled it down. Then as a test I stuck a few of our winter blankets we used off of our bed into the trunk. Drone cut down 50% but my wife is going nuts trying to find the blankets. It worked so well I don't want to tell her I got them. lol. I still get some coming from the back seat so I need to pull the seat and add some of the stuff you guys are talking about.

My fix makes the trunk useless but I don't carry anything in there anyhow. It doesn't weigh much either.

Not the best solution but if I ever break down I will be very warm and comfortable while I wait for the tow truck.

I guess it was'nt that bad to me.Injen, shorties and MRT V2. Key awas the resonated x pipe as I have said before, with or without the stock resonators, drone, very litttle, and more a very low performance growl, was the same as the magnaflow mufflers I had. All these exhausts will drone a bit, nature of the beast. And you dont add a bunch of wieght to the back, but the two may just do the trick.

Sorry I haven't kept you guys in the loop. Due to work and thanksgiving I wasn't able to start this helmholz thing up yet. But this Saturday I am going to my dads shop. He has a lift. I will take pictures and do a DIY. I will post my initial findings on Sat for sure!!!

Yes awesome thread. From the research I have done, the MRT2.0 eliminates the drone over the 1.0. So it's good to know there is drone to contend with.

I'm not to wise about exhausts. What's the difference between H and X pipes? Other than shape. Would one be better than the other in reducing drone. Looks like H pipes have better low end power; but appear larger and more difficult to install with limited space.

Also, is there a specific x pipe for the camaro or do people use the generic one? Where in the exhaust line does it get installed?

Typically for the V6, the traditional X pipe causes rasp...so when people want to reduce drone and/or rasp they will add a Resonated X pipe (essentially a muffler, with an 'X' shaped core and perforated on the inside as well) in place of where the stock H pipe is. It pretty much always helps quite a bit, but it can also muffle the exhaust tone some so there is a bit of a trade-off.

Good luck Mach....may want to do what SOLO does and make the ends adjustable so if your first attempt isn't perfect, you can make a simple change and correct it.

Well............. It took 4 hours but I got the pipes in. I got so lucky picking out the right mandrel bend sizes. These pipes are made by summit. I made them 29 inches long. I was able to package them super tight around the mufflers. Here are the pipes they fit perfect...

http://www.ebay.com/itm/390364088873...S:1123&vxp=mtr



Top of the muffler...



Bottom...










And I have to say the drone is GONE!!!!! What ended up happening is the really deep bass drone got eliminated. The stuff that drove me crazy at highway speeds (70-75mph)

Here is the before..



Notice how the 100-120 Hertz is flat now...

AWESOME job, glad to hear it worked out for you. Looks like you found a small side job......

MRT owners can send you their mufflers and you can install the pipes and ship them back...........

Great job. I've got all three pipes ready to go. Looks like I'll try to get this done when I can.

That is 29" from the weld to the cap, right? Any tips on getting this done before I try myself? I dont want to screw this up. I'm probably gonna cut the pipes myself to the lengths I need but gonna have to have a muffler shop do the welding. I haven't worked with pipes since high school. I do remember not to measure from the inside or outside of the bend but from the middle. You basically cut the two U pipes into J's, cut the bend of the last U in half to use those elbows and weld them to the ends of the J's. Not sure if that makes sense, but I'm just trying to spell it out for myself, I need all the instruction I can get.

Yeah, its 29 inches from the weld to the cap, down the middle of the pipe. I am going to do some solid highway driving tomorrow. (250 miles). So I will have plenty of time to take more scope clips and get a good feel for how 29 inches is working out. Or if we need to go longer on the pipes.

I just got my hands on a huge sawsall and put the pipes on a table vise. The way you explained the cutting is the way I did it. I would recommend the shop cut the pipes because it takes some test fitting%2

Sounds good. And sounds like a long drive. I am excited about this but I'll hold off until you're satisfied with the length. Since the new pipes are so close, they're not knocking against the mufflers or the spare tire well are they?

The highway drive was a success!! According to my scope app I lost about 10db. It doesn't sound like much but 10db is actually ALOT! My ears enjoyed it too. The drone at 75mph is totally gone! The MRT 2.0 now sounds just a bit louder then stock at cruise. But its still loud as hell when you step on it!!

The only time I got a drone is going uphill while keeping my speed constant. But that is still about 10 db quieter. Uphill before hit 86db now the highest I got was 76db I am totally happy with this mod.

Cruise at 75mph before was 82db now I get 72db....

This to me is the perfect exhaust.. It sounds mean like the MRT2.0 but 0 drone. I am able to listen to music at a quieter volume and have a conversation without the BRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!
