So I went to install my catless downpipe last night. But I couldn't get off one of the nuts on the gasket. The top one on the side of the downpipe that has three screws, the side on the opposite side of the midpipe. I'm wondering if there was something I was supposed to do, because it felt as if the nut had like melted into the gasket because of the heat from the cat. Any help would be nice, if all else fails, local performance shop.

Thanks guys

 

just break bolts and get new hardware at autozone

 

It took me about an hour to get those off of my 04 about 2 months ago. I was taking off the stock cat so those biotches were siezed in a good bit. You just gatta put some *** into it. I used a pipe on the end of my rachet for more torque. If you havn't tried that, then give that a try. I also had only the passenger side jacked up on blocks so I had more room to work.

 

I did the same exact thing dude. Didn't work.

 

ask some rx8 guys in your area to help out

 

LIke I said, I messed with it for a good hour. and WD40 the shat out of them. finally I got a long enough pipe that I could stand next to the car and crank it with all my weight

 

so cal lazyness break it and replace it lol

 

Ok. I should of used WD40. I think I'll give it one more shot this week. Call a few of the RX8 dudes over and do this. Thanks guys, I'll keep you posted

 

yeah, just break it, that would be easier. that bolt was a pain to deal with, eventually with enough force it came off on mine

 

This reminds me about why my car is so great. I change exhausts bi-monthly. All the bolts come off with barely any effort. The exhaust hangers are smooth like butter.

It was a bitch to get the cat off the first time though.

 

Breaker bar is your friend

 

So i guess one of the bolts was welded and the other was frozen on. This car is on its second cat, the owner before got his changed under warranty. Anyway, I got the new downpipe put on for $50 at a local shop today. Sooooo loud haha

 

And welcome to the flame club!!!

 

lol same thing happened to me.. and i ended up just taking it to the shop.

 

haha glad its not only me. I need some resonaters, asap.

 

ok so, i want to install a mid pipe 2, i have the hks cat back hi power. and i want to put in the agency power mid pipe cause its only like 220$. so will this bolt on? do i need to weld it. please help me???

 

it'll bolt on..

 

As long as you have the gaskets, you are good to go. Everything is bolt on for the exhaust.
