I am putting together a full performance exhaust system. I am looking for a really good Catalytic Converter. Can anyone give me some suggestions and maybe HP gain? Also, I am still curious about a good performance muffler. Not an expensive muffler, just a good performance one(Under $100). Thanks a lot.

EDIT - What length of catalytic converter do I need to get? Does it matter?

well for a cheap performance exhaust, you could go:

catco cat convertor - $50 for universal one or $100 for custom one
magnaflow resonator - $50
ES straight-through design muffler - $100-$150 (ES mufflers are stock looking)

then you gotta pay for custom piping, if you go for mandrel-bent piping thats more expensive.

 

What size cat do I need(length and diameter). Also what do you guys think of the dynomax super turbo mufflers?

 

What are your smog limitations if any, I would just gut your cat. Better than any other aftermarket cat you could get.

 

dynomax super turbo muffler is a great muffler and only about 40 US

 

I cant gut my cat, I auto-x and it would break class rules.

TTT

 

actually gutting your cat is not the way to go. if you want to keep it stock looking, gut it and put a piece of pipe in there.. otherwise you screw yourself flow wise.. the exhaust expands and then chokes up when it hits the pipe again.

i learned the hard way

gutted cat = 30% loss in MPG
