Hey whats up i have a 98 accord 2.3l vtec 5 speed LX, I'm thinking my car has a somewhat clogged up cat, but lets see what you guys think. when im driving sometimes my car will be steady at 3 rpms and just start bogging down until i shift into the next gear and then it stops for a while. im also getting a little bit of grey smoke out of my tailpipe when i hit like 4.5 or 5 rpms. if it is my cat i was thinking about hollowing it out untill i got a hi flow cat, already have dc headers and apexi ws2 exhaust. any help would be appreciated. Thanks, Nick
