[QUOTE=scrming;1433938]Would love to see some independent dyno testing... no one, including me, is immune to the placebo effect!!! I could have sworn I picked up some nice gains with my JBAs and a tune... but the dyno proved me wrong... all in my head! LOL! So needless to say I tend to be the Doubting Thomas when [COLOR="Red"]folks say "WOW, my new mod made a big performance gain!" And that's why i will continue to buy dyno time and run my car at the track...[/QUOTE]
....EXACTLY........!!!!!! The only way to tell of ANY performance gain is #1..Run with the same (or very close to the same DA) at the track, #2..use a timing device,it doesn't have to be 100% accurate just CONSTANT. or #3..Use a dyno......BUT ALL testing MUST be done with the same or very close DA (DENSITY ALTITUDE) ...... IMHO !!! |

Even with the wind noise in the video, I could pick out the exhaust sounds fairly well. I think it sounds great and if I owned a V6 instead of the V8, I would seriously consider this system. It's got good tone but fairly quiet too which is a good way to mitigate the honk or raspiness that alot of folks notice with this engine. Even my 09 Malibu with it's 3.6L had that same honk at higher RPM with WOT. I figure if GM can't completely tune it out, it's going to tough for the aftermarket exhaust guys too. Good job!

well... if you think we talk about rasp a lot now, i have the feeling we'll be talking about it a lot more once people start putting long tubes on...

Also agree that while yes the rasp issue has been beaten to death, the talk about it will never just go away b/c in my opinion, getting rid of as much of it as possible is why some people want a new exhaust in the first place.
No exhaust may ever completely eliminate it, but I think these magnaflows do a fine job. Appreciate all the feedback and looking forward to your future vids FishTail!

This is my unbiased opinion because I sure have nothing to gain or lose whether someone buys Manaflow or any other exhaust, but it is an opinion none the less.

The "Third" muffler is a resonated x-pipe. It has a tru-x perforated core and it's packed the same way the mufflers are. The high quality packing Magnaflow uses is the reason they sound and perform the way they do as well as having a lifetime warranty, the sound doesn't change much over time. They will get a bit deeper/louder as they break in but after about 2-3K miles it will stay the same. Quote:

The 4.0 Mustang motor is probably more similar than you think... their dyno graphs are about identical until about 4,000 RPM where I believe you start seeing the VVT really shining on the LLT... at that point the LLT graph takes off...
Also.. you mentioned the perforated x-pipe... found the diagram for that: I have the feeling that this x-pipe is really absorbing a lot of sound along with the two mufflers... giving the system it's refined but quieter sound...

You're correct, the resonated x-pipe acts like a muffler and helps control the tone. I personally think the Magnaflow cat-back has the deepest/smoothest tone on the LLT and it's my favorite. Kind regards, |

Cat-pipe-cat is probably not the best setup... LOL

So much to consider with all of these systems out there.
I really am leaning towards the Magnaflow cat back because it does seem the most well thought out. I am hoping it is a little deeper and louder than stock, and the video here does give me some hope. Being up here in the Rust belt, a COMPLETE stainless system is the only way I am going to go. The one downside I see with the MRT stuff is the Chromed tips which if not watched out after will tarnish and rust after time. This is one reason I perfer the polished stainless steel. I'll have to wait anyway, Taxes are not going well and I owe a TON due to taking some of my lump sum when I got downsized to tie me over this past year, the with my parents passing away and the inheritance taxes, I'll be tax poor this year. Glad I bought my Hurst when I did! I might not have bought that at all. |
