okay, i posted this in the newbie tech thread but not enough attention, i need some asap because i can go cut this out before i have to be at work. 88 rx7 vert with a turbo 2 exhaust. workin on doing a major tune up. plugs, wires, royal purple oil change, oil filter, air filter change.. but recently the exhaust system has been acting up on me. here is what i wrote on the other thread:


well the line from the mid cat to the engine where i suppose exhaust runs through or is recirculated back to the engine...the high temp hose near the cat burned up and fell off.

i've replaced it a few times and it keeps melting away. so i thought the cat would be clogged...also before that started burning up around 5k ~ 6K rpms i'd get a bit of a sputter, lack of flow through the exhaust(clogged cat)? new plugs(did that)? injection problem maybe(going to use some cleaner next time i get gas, using 87 octange btw.. i heard that was good)...

i put some royal purple and that feels great. i was just curious how well that would be for the engine considering it has 122k miles.

uhm..soo.. should i cut that cat? if i do.. i'm guessing i need to weld the 90 degree angle part that comes out of the cat into that hose and pipe leading to the engine?

just trying to figure somethings out about my fc. thanks for the help and checking it out.

 

any ideas or help? i was going to do this today before work if i could, so let me know.

 

kk, going to work. i hope to see something when i get back from work D: plz?

 

Are you talking about the METAL split air pipe?
