which would sound the best not to annoying and or give me the most power i have a magnaflow catback 2 1/4 piping and will be getting a megan header

 

Voted for having a converter...

didnt notice any difference in power (I know... butt dyno BS) between the two.

I prefer the more subtle sound of a high flow, you wont get busted for the smell pumping from behind your car, and you help the EVERYONES HEALTH just a little bit.

They are cheap too...

when you get rid of you cat it is going to sound really really ricey unless you get a good set of headers. I vote don't get megan headers. just save the 85 you spend on the megan headers, and you should get some dc at least.

but if you are going to get the megan haeders go with the high flow cat, but that is just my opinion.

 

If you have emission testing get the hi-flow, otherwise get the test pipe.

 

I voted for hi-flow cat. The noise is significantly reduced so you dont drive around sounding like shitty farts all the time. Not only that but you can get 'CARB legal' ones too

 

hi-flow all the way.

 

no point in a test pipe unless you're turbocharged. a large, high-flow cat will almost flow like a test-pipe at low pressures. i doubt you'd be able to measure the difference in flow between a 2.25" converter and a 2.25" test pipe as long as the converter is new and of decent quality. i picked up a 2.5" converter just to make sure it wouldn't be a bottleneck.
