I got the megan racing resonated testpipes and megan racing Y pipe. The install was a breeze except on the driver side cat, one of the bolt was hard to get to from the bottom so we had to get it from under the hood. I am currently using my stock everything after the ypipe so it still has resonator and stock muffler. Sounds real deep and smells haha. One thing you should know if you plan on getting it, is that the y pipe may loook like it won't fit at all. If the installer says you have to cut it or it doesn't fit, then tell them to just go ahead and flex it and try it out. ONce you bolt up one side, the other one flexes or stretches a little and it fits perfectly. FItment is good and gains are noticeable. THe check engine light won't come on for about 100 miles but after that there is a "service engine soon" light that comes on. I'm trying to make a simulator to rid of that annoying light..but other than that, i love it. I can't wait until I get my exhaust. Pics to follow...

 

So everyone running a test pipe is driving around with the CEL on?

 

Well I have heard that pre 05 models don't have it on. I forgot to clearify that I drive a 2005 6mt sedan. Just wanted to get the info out there since not much 05 people (let alone a SEDAN) are jumping on the modding wagon..

 

IS there any rasp at all in your current setup throughout the rpm band? Also what kind of headers are you running?
