Guest szlash280z Posted August 29, 2003 Share Posted August 29, 2003 my local shops seem to only carry MagnaFlow, none carry Dynomax. I was playing with one of their MagnaFlow straight thru oval shaped mufflers today, it was really high quality. it didn't have the cheese grater crap like those resonators I was looking at. Anyone ever run one of these MagnaFlow mufflers? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 29, 2003 Share Posted August 29, 2003 Isn't Magnaflow made by Dynomax??? Jon Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted August 29, 2003 Share Posted August 29, 2003 I don't think so, DynoMax makes the UltraFlo muffler, I don't know if they are affiliated with MagnaFlow or not. Quote Link to comment Share on other sites More sharing options...
Guest Zrac3r Posted August 29, 2003 Share Posted August 29, 2003 yea i run a magnaflow..and its loud..mainly because i dont run a resonator so its just a straight pipe back to the muffler. but before i cut my resonator off it wasnt loud at all Quote Link to comment Share on other sites More sharing options...
Guest Bamm Bamm Posted August 30, 2003 Share Posted August 30, 2003 Magnaflows are great flowing mufflers i think the only ones pretty much that flo better are the Dynomax UltraFlows.. I have a 3" in/out magnaflow on my sierra and love it Quote Link to comment Share on other sites More sharing options...
Guest Bamm Bamm Posted August 30, 2003 Share Posted August 30, 2003 OH ALSO Magnaflow makes 3 lengths 14" really loud, 18" kinda loud and 22" nice and deep sounding.. I like my 22" on the truck Quote Link to comment Share on other sites More sharing options...
Guest Carrman Posted August 30, 2003 Share Posted August 30, 2003 I run a Magnaflow on my 75 turbo with no resonator. Nice throaty sound, not obnoxious at all. I like it! Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted August 30, 2003 Share Posted August 30, 2003 I run a "street series" Magnaflow muffler straight through design w/ a 4" tip. I run hearders and 2.5" pipe and it's LOUD above 3k. But i love it Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted August 30, 2003 Share Posted August 30, 2003 are you guys running turbos or NA? my turbo isn't that loud without any pipe. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted August 31, 2003 Share Posted August 31, 2003 NA with a cam Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted August 31, 2003 Share Posted August 31, 2003 cool, N/A engines with no mufflers are much louder than Turbo's for some reason. So the magnaflow in theory should muffle it fine for my turbo engine. (I hope!) Quote Link to comment Share on other sites More sharing options...
Guest Carrman Posted August 31, 2003 Share Posted August 31, 2003 Magnaflows work very well with turbos, my '75 likes mine. Deep, mellow sound, but still free flowing, just don't let them talk you into a resonator like the muffler shop tried to do with me. He was amazed how quiet mine was when we were done.

Moridin Posted September 5, 2003 Share Posted September 5, 2003 Turbo motors are quieter, because the turbo itself muffles the exhaust noise. On the Magnaflow note, they are really good mufflers. The resonators are supposed to really help with noise suppression if you are interested in it. Borla is another good manufacturer. They make the same type of non-louvered, straight through muffler. The Magnaflow stuff on NA motors seems to be quiet off idle, but then really open up as the motor revs higher. Like I said, the turbo will quiet it down, so you won't need to worry about it. Edit: Forgot to add something. Quote Link to comment Share on other sites More sharing options...
Guest szlash280z Posted September 5, 2003 Share Posted September 5, 2003 I had mine installed, 3" pipe, 3" in out magnaflow muffler. It has a very nice idle sound, and it is very very quiet even when jumping into the gas! The magnaflow muffled the crap outta my engine! It's kinda nice!

Guest Anonymous Posted September 12, 2003 Share Posted September 12, 2003 What do you guys think about Flowmaster? I have a turbo. Will that be too loud at 4000RPM ? Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted September 12, 2003 Share Posted September 12, 2003 What do you guys think about Flowmaster? I have a turbo. Will that be too loud at 4000RPM ? DON'T use a Flowmaster with a turbo. For one, they don't flow well, and two, they resonate horribly (chambered style). I hated my chambered muffler for those two reasons.

Moridin Posted September 13, 2003 Share Posted September 13, 2003 Depends if you get the three chamber or two chamber design. With exhaust, as I understand it (especially with turbos) you want nothing blocking the gasses coming out. The Flowmasters have "chambers" that change the sound to that nice rumble, but block air flow. Magnaflow, Borla, and I think Dynomax, along with others make a straight through muffler. It keeps the gasses flowing and makes for a good sound. Magnaflow isn't that expensive, is quiet on idle, and they all carry a lifetime warranty. The turbo will keep the exhaust quiet too. The Neon SRT-4's have no muffler, which is a testament to how much a turbo can quiet a motor. Quote Link to comment Share on other sites More sharing options...
Guest jjohart Posted November 21, 2003 Share Posted November 21, 2003 Hi, my exhaust installer isn't really telling me whether to use the Manaflow straight pipe exhaust or the street style. The site has two or three different model lines...can anyone tell them apart for me, like loud, louder, obnoxious (definitely don't want the last!). I'm running an 83 280ZXTurbo, about to put on a custom exhaust system, and this last piece should be obvious from other replies already here, but I don't see the different models being named (the web site doesn't even have sound files for the straight pipe muffler!).

Garrett76Zt Posted November 21, 2003 Share Posted November 21, 2003 Ivan and I are running nearly identical exhaust setups. We both have 3" from the turbo all the way back. He is running a Magnaflow and I am running a Dynomax. The cars sound nearly identical. My car sounds beautiful at idle, nice deep rumble and really isnt very loud at cruising speeds about 2800-3000 like on the interstate. The only time that it gets loud is when first accelerating at like 2000 rpms or so, then once the revs go up the car gets quieter. Anyways I love it and it certainly made a performance diff.

Guest jjohart Posted November 21, 2003 Share Posted November 21, 2003 ..so what is the Magnaflow trade name for the style of Magnaflow muffler...is it a straight pipe muffler (which I think is called Street straight or something), or one of their other lines? Thanks John Quote Link to comment Share on other sites More sharing options...
