I'm going to get new mufflers soon and I'm tring to decide between Magnaflow and Dynomax Ultra Flo.  I've already heard the Magnaflow's.  So, does anyone have a sound clip of the Ultra Flo's on a TGP?  If there is someone out there that has owned either one (or better yet both) I'd like to hear likes and dislikes.  Thanks.

Luke, did you use offset in/out Magna's with the stock system? I gutted my cat also and have dual 3" polished stainless tips per side (JC Whitney) that look awesome!

so you've got these tips http://photo.starblvd.net/mfewtrail/2-2-4-1058318547?m=1&pg=1&ro=1&co=3 ? :wink: ..they look big in pictures but actually fit nicely..I've seen a few people w/ the same style but 3.5'' outlets on B4U equipped cars...got any pics of the TGP showing the rear?  As I said elsewhere, I believe the ultra flows by dynomax outflow most other mufflers so that would be my choice for a turbocharged car, but the magnaflows Luke have sound pretty good as well...I think both would have about the same sound to them as magnaflow and dynomax both make quieter/tuned sounding mufflers opposed to other companies that make louder mufflers..I'm sure both companies offer racing mufflers as well(the bullets from dynomax I know of..but they like to fail).

Any others out there that can offer an opinion on either of these mufflers?  I'd like to hear from a few more people before I make a decision.  I'd also like to hear if you had a really good experience with another brand as well.  Thanks.

magnaflow is a really really nice muffler.


if you dont mind a louder car though and law allows just dont use mufflers and get some nice straight pipes with unresonated rolled 3" tips for the ends.  Also rip out the heat shields in the exhaust cut-outs in the bumpers, makes it look 100% better.

No mufflers is out.  I really want the low, somewhat quiet, deep rumble and I heard that both of these mufflers will give me that.  So far it seems like a lot of people prefer the Magnaflow's.  The only thing that I see that makes me want to go with the Dynomax mufflers is their flow numbers.  They are really impressive.  I would still really like to hear a sound clip of the Dynomax's.
