Anyone with a Magnaflow Cat-Back System?

Chris03hd · 02-26-2006, 06:56 PM

Just looking for some likes & dislikes from those that have, or have listen to one in person before.

TIA!

I don't think you will find too many. Lots of people are running magnaflow mufflers, but I think the cat back does not replace the y pipe which is why there is a lack of interest. If you are looking just for sound and no real added performance then just clamp on a new muffler. Don't waste the cash on the Magnaflow system.

I have the magnaflow, so called cat back system. I had to buy Banks 3" from the Cats and Y pipe for an extra $200.

Dude you kill me; you must have slept at a Holliday Inn Express last night! I have a Magnaflow catback and love it! Although I have not dyno'ed I think it performs on par with most other systems Y pipe or not! (I've driven both Banks & flowmaster equiped trucks) There are a lot of folks that like the nice Drone of the Banks or the Mustang-GT'sh shriek of the Flomaster but I prefer the rumble of the Magnaflow. I don't think I have seen a dyno yet that show a (significant) increase in TRQ/HP by changing the y-pipe, at least not enough to keep me awake at night!

With the Magnaflow system, without the Banks 3" Y pipe, I ran 15.34 at 89 mph, same as I ran stock. I changed the pipe to 3" from the cats back, and installed the Banks Y pipe, ran 15.15 at 92.84 mph.
The 3" piping and the Y pipe had more effect than the muffler and tail pipe.

Kyle at Stillen said to me, they showed ZERO gains with all different combo's while testing Y pipes for our trucks... In fact, he said they LOST some power on some.

Your drag strip number are improved, but there are lots of variables (i.e. track conditions, weather, air pressure, etc., etc.) that also played a part in your new numbers... Unless you made sure the exact conditions (or close to) were made on the next runs, it means nothing.

Im sure you knew that, but others make me laugh when they "test" a certian part in the summer, only to change it out and test something else in the fall, and BAM!, its this huuuuge improvement.

Thanks for the scoop from stillin, I trust there word more than some guy that's still runnin a stock system!

The two trips to the track were two weeks apart last May. Temps were in the 60s both nights. I am convinced that the 3" Y pipe made the biggest difference of any thing that I have done to my Titan.

You must have stayed at the same hotel I did, because you paid the same price for a system with less metal!

If you weren't going to replace the y-pipe you would have saved a SH!T load of money buying the muffler and a tip. Ha ha you paid over 430 bucks for a muffler and a tip!

I'd be pissed if I paid that for a muffler and a tip. Explain to me then if the y-pipe makes no difference why you paid 430 bucks to replace the only restrictive part of the eqution left,,,,,,,,the muffler???????????????????????

As far as Stillen goes, did they test with or without intake or just exhaust?

Very helpful man, that Kyle Millen is.

This was the extent of our PM when I inquired about the Gibson, so I cant answer your question about testing done with or without an intake.

I am curious why you are so specific about looking for the Y-pipe on the exhaust. Our testing shows that the Y-pipe does not gain any power, and actually causes a loss of power.

My thought was that if you advertise and sell a Cat-Back system, it hould be a Cat-Back system, not just a muffler and tail pipe. I build and dragrace motorcycles, not trucks, but I will take track results over dyno results anytime.
All that being said, I think that the Magnaflow muffler and Tip are very high quality material and even though the combination Banks/Magnaflow system cost $650, I believe that I would go the same way if I had to do it over agin.
And by the way, I called Magnaflow, before I ordered the system, and asked if it was a complete cat-back system, and was assured that it was.

Actually I paid $286.00, that should make you feel a little better. I got the magnaflow muffler, 3in pipe from the cat & stainless tip installed! and it all works rather well.

And as for compairing HP/TRQ changes with different mods, I would think the dyno would be a more controlled invironment i.e. limiting the impact of variables such as temp, wind, humidity, reaction times etc..etc..

All-in-All all this doesen't really matter to much to me because i'm happy with what I have, and everyone want's to think they have a good system. it's just not right when make blanket statement based on questionable at best info.

Oh yea Banks, Flowmaster guys, sorry for the wise crack. I listened to "imagine" last night an started to feel really bad.

Wait I am confused, you said you have the magnaflow system. If you got the packaged system you do not have a pipe from the cat. You got a muffler, pipe from muffler to tip and a tip. My first post was saying that many people used the muffler, but not the "cat back" system which sounds like what you did. Did you mean 3 inch from the tip in your post? Did you actually get the system or just a muffler, pipe, and tip. That makes all the difference in the world. I have seen the "system advertised for 430 bucks which is a rip off. That is what I was trying to say in the first post. What you paid for what you have is absolutely fine. Does that make sense?????

I have the Flowmaster 40 catback single in/dual out, and my Dad just put the Magnaflow (not sure which model muffler) kit w/ dual rolled resonator tips. When they were welding his kit in, they said his would have more torque than my flows because of a better quality kit. I agreed that the kit was much better quality, but I shut him down when we hit it on the way home. I also have more weight on my truck (brushguard and utility bed toys).

Aside from the performance, I love how both kits sound. His sound is more of a controlled rumble, where I have the classic loping Flowmaster sound. At WOT I am MUCH louder, though.

Oh yea, he has an 06 SE KC O/R and I have an 04 SE KC O/R.
