I love the way my magnaflow sounds, it is not too loud, but the rasp in the higher RPMs makes it sound horrible. I'm checking out Summit right now and I am looking at some 3"in/3"out 18" round case mufflers.

Is there anything else cheaper that will take care of the rasp? I know alot of guys run dynomax bullets to get rid of rasp, but do they work very well? I want a proven muffler/resonator to use that is a straight through design, and it would help if it was cheap, but I am willing to spend the money if it will work better than the cheaper products.

I've also been considering an slp loudmouth or maybe even a small borla xr-1.


I do not want it to restrict the exhaust flow at all either.

 

just do another muffler or a magnaflow resonator, my brothers tbss was too raspy but great sound! He added a 14" round race series magnaflow and it sounds great!

 

These are the ones I'm looking at so far.

I've heard the same complaints on other boards and one solution there has been SpinTech. I havne't looked into it, but those that have switched from Magnaflow are loving it. Great sound, no rasp, no drone...

 

I don't want to switch mufflers or go to a chambered design (already had a flowmaster). I am happy with my magnaflows performance and its sound (even with the rasp it sounds pretty good), but I would just like to get rid of the rasp and have a smooth aggressive sound all throughout the RPM range.

 

i was also looking at the spin tech mufflers, i have to get rid of my dented up flowmaster.

 

i run no cats and a magnaflow! I love it although when cold its raspy! I highly recomendt the magnaflow dual inline muffler set up! idk about the slp might make it too quiet! ??? never heard that setup!

 

My friends got one on his stock 5.3 out the back with a corsa style tip.

It sounds really good, but to me it is louder when he lets off the pedal and RPMs go down than when he is giving it gas.

 

well maybe not, i just read alot that says spin tech is alot more restrictive then magnaflow... i want something that flows good but not as loud as my flowmaster

 

Get a round case magnaflow.
