it steps down to stock cat size

 

Is anyone running the Magnaflow Catback with a tune and if yes...what returns have they seen. Is it an ECUflash or Cobb tune.

Thanks

 

I was running my Magnaflow cat back with a Cobb stage 2 tune first, then I went with a custom tune. Mind you I have full turbo back with long downpipe.

So on a stock tune with exhaust I was doing 218 awhp. With a tune 250 awhp. Here in Calgary we are at 3500 feet above sea level. So that makes it even harder to tune turbo charged cars. Also, that dyno was showing 10 % less than it actually was. Just because of that particular dyno.

 

yes... I'm running a personally modified GST Basemap Boostpill tune on my car:

 

I had that part cut out and made to be 3" the whole way.

 

Yes good idea. Are aftermarket HFCs and test pipes 3" at both ends or do they step down to the down pipes as well?

 

my GSR 2011 put down 315 WHP at 25 PSI after the tune.

Magnaflow CBE, UR mini muffler test pipe and Works drop in. Cobb AP tuned.

 

I have Ultimate Racing long downpipe and HFC, they remain 3" even at the flanges. Only the Magnaflow had a smaller bottle-neck where it connected to the cat. I cut that out and replaced it with a 3" piece/flange.

I'm currently putting down 291whp/310wtq with full bolt-ons and a Works high flow panel filter (no intake).

Soon, Rad Lite. I'll post those results with above bolt-ons.

 

I bought an magnaflow exhaust for my ra and I have to say I would just stand there and listen to it for minutes on end. For the money you can not go wrong.

 

I recently bough the Magnaflow to replace my DC Sports exhaust.

Very impressed & thanks to a member here sharing coupon codes from a vw forum I saved $146.xx.

Total cost after shipping and taxes was $505 and being in Canada that was hundreds less then anywhere else.

 

How does the 2 cat backs compare sound-wise? Which one was louder? Which one had more droning inside the car?

 

I would say the DC Sports was a little more 'throatier' but still tame compared to UR & Borla. The DC Sports had zero drone, driven on a few 2-7 hour rides and it doesn't drone like many aftermarket exhaust. I would not advise anyone to purchase this exhaust based on the fitment issues alone and the complete lack of customer service, thoroughly dissapointed and I will never buy another DC prododuct again.

The Magnaflow looks much more stock as it has oval tips, which I like but it's up to personal preference. At idle it's as loud as the DC sports, maybe a touch quiter. Daily driving it's pretty damn quiet as the DC Sports one was, but when you stomp on it, it wakes up. I have not noticed any drone but I've only had it on for a week.

FYI- I've got a 3: resonated test pipe which has been on for both systems. Also note that I was happy with the look & sound of the DC Sports and wouldn't of switched if it wasn't for the poorly made midpipe which made the resonator make conact with the driveshaft.

 

Edit... never mind, saw you are running UR highflow cat.

 

On my exhaust, I am running a depo hfc. For the price they are hard to beat. Really happy with it.

 

I have the Magnaflow (with stock cat) and completed a cross country (California to Florida and back to California) road trip with it this past June. It did not drone at all the entire trip.
