Default which muffler flows the best?

my b-day is coming up soon and my parents said nothing over 100 bucks, so im looking into getting just a replacement for the OEM muffler I know I wont get an insane hp gain, but im sure it's some better flow and sound

I went to summets web site and there are a couple brands but I want to know which do you think is the best bang for the buck

http://store.summitracing.com/egnsea...922711&NeXID=5

the ones im looking at are Hooker, Flowtech, Dynomax and Magnaflow which is the best?

thanks

Dynomax UltraFlo flow very well and I believe Magnaflow has very similar construction. Sound is deep and not annoyingly loud.

When I was planning the heads and cam a lot of guys told me the dual 2.5" dynomax Catback I have was going to be a choke but I gain less than a tenth opening it at the track. I have resonators too and actually get comments on how quiet it is for a car making the power it does.

I have a hooker catback on mine. I love them. Second one I've had. Sounds good but not extremely loud. Brother has magnaflow and it sounds good also.

Honestly, have them give you the 100 and put it towards saving for a catback. Since that doesn't answer your question though, I will say that Hooker's sound very nice, probably what I would put on a stock exhaust...

The Loudmouth 1 Resonator Muffler is basically a hollow 3" can with SLP letters on it.
There is absolutely NO restriction.
I don't see how you could get any more airflow then that... maybe a 4" inch can?

I put a magnaflow muffler only on my sister z and it sounds good. I got a magnaflow catback waiting to go on as soon as I can afford headers.

Try and get the Loudmouth used in the 'parts for sale' section.
The Loudmouth is basically the closest thing you can get to 3" Straight pipes and be legal, plus its 3" stainless from the cat to the axle, then splits Y's into 2 1/2" outlets.

You will not be disappointed.
I got my entire LM1 for $185 used.
Just make sure its not cut-off.

Brand new they are $380

Well this is just straight pipe with tips and a gutted cat, hope this might give you a idea of what it sounds like before any muffler is installed...
