Hey Guys just wanted to share my latest project. I installed the new Magnaflow Street Series catback and it sounds great with a nice deep tone with absolutely no rasp at all.
Videos Here. Sorry it was a very windy day

Just want to say that Jordan and the guys at Magnaflowplus.com - JDP Motorsports, took realy good care of me. They gave me a great price on this system with super fast Fedex shipping and if anyone of you is intrested, you should contact them before the end on January so they can hook you up as well.
The price is too low to post, just contact them and you'll see.
Guys If you want 0 raspiness through the whole RPM range this catback is the way to go IMO.

Love the sound of your cat backs...forsure! Too bad by the time I'm ready to purchase (something), these will be back up over the 1000 dollar range. The axel back version sounds close to yours from what I can gather through the video on here, but perhaps with a bit less depth to them.
Agree, I hear no rasp in your vids at all!

There was a LOT of testing with the 4.0L V6 Mustang which had 2.25" down pipes to a Y pipe which then goes to a single 2.5" pipe for a single exhaust. Dynos showed minimal gains going from the single 2.5" pipe to 2.5" dual exhaust... so moving from dual 2.25" to dual 2.5" would most likely show the same minimal gain...

The 4.0L Mustang engine was making a 1/3 less HP than the LLT 3.6L and they are both completely different. I'm not saying you're going to gain a lot going from 2.25" to 2.5" but the design of the Magnaflow mufflers and resonated x-pipe will allow for better flow as well as tone quality. You're correct that the factory exhaust manifolds and converters are the largest restriction in the system but a cat-back does help. As you know an engine is basically a large air pump, the more air you get into/out of the engine the more power you make along with added efficiency when your foots out of it! :bellyroll:

The raspiness is the nature of the V6, not the resonators... I think the reason you have less rasp is because you've "muffled" it... Hard to tell from your video clips, due to the wind noise.. but definitely sounds like your setup has a much more "muffled" sound than other systems... Doesn't have the louder, free flowing rev sound... I'm not saying that is a bad thing, just my observation and opinion....
So looking at the diagram... the H-pipe and resonators are replaced what appears to a 3rd muffler... I know it's not... but can't think of the proper name... but I think it definitely is going to quiet things down more than the resonators.

I don't know about the mufflers but they appear to be chambered and guessing probably going to be on the quieter side...
So like I've always said, exhaust sound preference is a very personal choice and if you like your system that's great! However, I think the real reason you have less rasp is because the exhaust is a less aggressive, quieter setup... best way I can describe it is "muffled"...
Think we need to line up all the different systems at Camaro FEST.. record them all with the SAME camcorder and measure them with the db meter from the same distance...

The Magnaflow system uses straight through polished stainless steel USA made mufflers packed with basalt (Lava Rock) and stainless steel wool mesh. They are as free flowing as you can get and honestly the best mufflers on the market. The sound is determined by the length and size of the muffler so you can tune the sound to your taste but Magnaflow spends a lot of time developing these systems to make more HP and sound nice. Everyone has a different opinion on the sound they like but to me this is a very refined system.
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.

Oh, and one other thing about the power gains...I've noticed the guys getting the flowmaster exhaust are noticing noticable power increases. While that exhaust also seems to have a nice low tone at idle and low rpms, when under a load or reving it certainly does have rasp....hence I'm guessing its a more free flowing exhaust than these magnaflows....and thus explains the power gains.
I really like the idea of getting the gains that FM guys are talking about, but I think I'd rather have a good sound than bigger gains at this point.
So my question is, have you noticed any differences in power or torque at all, or is it more of just a noise change?

The Flowmaster is a chambered muffler meaning it has restrictions. That is why you get that tinny noise with FM. The Magnaflow mufflers are straight through and they cause no restriction, the restriction is the pipe diameter.... I'm not sure who is seeing large HP gains with FM but I've always seen the opposite. On our 73' when it was N/A we picked up 25 RWHP (bring us to 525 RWHP) changing the Flowmasters with H-Pipe to Magnaflow with X-Pipe. The power was also a lot smoother.
If anyone has any questions please feel free to call, email or PM me anytime. Have a great day! :chevy:
Kind regards,
