Right now I have a straight through pipe in place of my CAT. I also have mac headers and a Magnaflow exhaust. The car sounds too raspy in the higher RPM but sounds decent at lower rpm...

Im deciding on getting a cheapie cat made up or possibly a dynomax bullet muffler made up there, I just can't decide which. I have a friend with a stock cat that I can swap in to do emissions if needed...

Can some people post some testimonials on the bullet muffler cat mod? I'd like to know how it sounds at WOT compared to !CAT...

 

I have MAC mids into a Dynomax race bullet, Then straight out to the
rear . No mufflers and no cats . Lets just say I have never heard another
LT1 like mine

 

the bullet will get rid of the raspy popping, will not quite the car however.

 

since its on topic, would any bullet muffler in place of the cat be good to eliminate raspiness and not bottleneck the flow? like dynomax vs. magnaflow vs. twister muffler (not sure if its a bullet)...would any of these work??

 

I have a Dynomax bullet in place of the cat on my car with Mac headers through magnaflow catback. I think it sounds very nice and does not have any raspiness. However, I dont know what it sounds like compared to a straight pipe since I have ran the bullet since I installed the headers. I say use the bullet.

 

will this work? http://store.summitracing.com/partde...5&autoview=sku


I'm putting kooks LT's , ory and have a corsa exhaust.
If I put the that muffler its going to refine the sound a bit and not going to make it louder than its already going to be with the long tubes right?

 

A highflow cat will do just as good of a job in taking away raspiness and popping.

 

would there be any performance loss with dynomax versus straight pipe? top and bottom end
