Default Magnaflow vs. Flowmaster

Just sold my C5Z, cammed, LG LTs, stock TI and picked up a bone stock C6 and it is a bit quiet for me. Looking for some thing a little calmer than the z but want to know I'm driving a muscle car. I like the look and price of both the Magnaflow and the Flowmaster. I know that the Magnaflow is stainless and the Flowmaster is not.

Is the Magnaflow worth double the money of the Flowmaster?

I haven't see either in person but are the tips on the Flowmaster cheap looking?

I can't tell too much from the pics I've seen. I'm looking for a nice looking, inexpensive quad tip exhaust, nothing loud like bullets etc.

Thanks for the input.

Just had a Magnapack (mildly aggressive full catback system including X-Pipe) put on my '05 M6 Z51. LOVE IT! Two large tips rather than Four (which I like but all may not). No sound clips but here are some pics getting it installed at Carlisle a month ago....Good Luck! (dont mind the Borla t-shirt the guy is wearing.... they install different brands)

I would stay away from Flowmaster, they are not stainless and I really dont like the sound either. I would suggest maybe the B&B Fusions, quieter while cruising and very throaty when you get on it.

My mach 1 had magnaflow and it was an excellent exhaust and sounded great. I've got the SLP Loudmouth 2 on my C6 and have been very happy with both the sound and the price.

The Magnaflows are really nice. Not overly loud, no drone, nice sound that doesn't cause the neighbors to throw empty bean cans at you.

Yes. Yes it is. Unless you own a mustang, then you get flowmasters and they rot out in a few years and you replace them, lol. I owned a mustang ( and hence flowmasters) before. Fail. Just get Magnaflow. They are nicer, sound better, and give more horsepower. My friend had a Corsca on his LS2 GTO. Sounded great until he cammed and ran LT's. Then it was just obnoxious. He switched to Magnaflow and it was perfect.

would the drone of the magnaflow be anything close to what I had with the C5Z's setup?

I had Flowmasters once - on a pickup truck, where they belong. Sorry, just not a fan of low rent exhaust on a Corvette.

Again +1. I think it devalues the car amost as bad as putting 22" rims and lambo doors on it.

I suggest zo6 mufflers (modded mufflers or even the mufflers without the mod done to them). Quiet or loud with a push of a button...and the sound is pretty unique. Plus it's cheap, you can find a used set for 350 on here? I did the whole manifolds to mufflers conversion on my c6 with zo6 parts and spent less than 1k including installation...i think a magnaflow catback costs more than that (1000-1100?).

I have headers and no cats. At 65mph I want to open the window and jump out.

Everyone's always concerned with sound and looks. Another thing to consider is the efficiency; whether the system performs well with high airflow exhaust evacuation. IMO that is the important thing.

Unless you want it to sound like every Silverado you see....I suggest the magnaflow.

Think I'm going to go with the zo6 mufflers and retrofit npp kit. Just seems to be the only way to get the beat of both worlds for under $1000

I have the Magnaflow cat back with X pipe on my '06 6 manual.. Absolutely no drone at all. Nice fit and finish and the tips polish up to a high shine. The sound is a more refined sound, not kid muscle car or the Mustang like sound of a Borla or Flowmaster. Plenty loud enough unless you must have attention getting noise.....I got mine used for a pittance. Heck, all the pieces had been individually polished & wrapped for me and the guy tossed in a brand new K&N set up to seal the deal. I say go for the Magnaflow with quad 4" tips, you will not regret it...

you cannot compare Flowmasters to Magnaflow. 2 separate breeds. As for me I only run Magnaflows on my 07 AW Z51 C6 and andon my 96 IMPALA SS.
