Ok so ive developed an exhaust leak right at the flanges of where the catalytic meet the y-pipe. What are my options on getting this fixed? Should i just get new flanges welded on? I dont think ive seen any aftermarket y-pipes for these cars so maybe get a custom one done? I lve put muffler cement in between before and it worked for a few months, but it came back the other day. Thanks for any suggestions

i was dealing with probably the same issue....i just got mine fixed the other day (partly because i was trying to hold off on fixing it till i changed my headers out and partly cause i was being lazy....so lazy i havent even updated that thread showing i fixed it lol).

i emailed Paul at PPE and ordered a flange/gasket/small section of pipe from him and had it installed, so far no issues

dont go aftermarket Jbrady swears 99% it will lose power BUT if you do i wanna buy your Y pipe so i can have one made by the only guy ever to make power from building one

i looked at it the other day after being under the car, it def isnt the best welding job ever (took it to a local exhaust shop) but as of right now it is doing its job so i cant complain

SIGHHHHHHHHH spoke to soon, CEL on today.....going to my buddies shop so he can show me how to smoke test my car and im gonna see if i can find my leak. if no leaks the only thing it can be is the cats i think as ALL 4 of my O2 sensors are new

i mean i need to look over some hoses and stuff but otherwise not much left it can be if no leaks
