hi. what makes you think your flex pipe is leaking? first off i have no idea what part 53664 is or where your looking at the part. but heres some basics. your going to need a jack and a set of jack stands. you can probably look online to see where they should be placed. your going to need a ratchet and sockets. im almost positive the flex pipe isnt sold as a separate piece so youll need the whole intermediate pipe. #3 in the link 2006 SUZUKI FORENZA Parts - Suzuki Car Parts Catalog Online Store
youll also probably need parts #2 and #4 just in case your gaskets arent any good. now comes the bad news. exhaust bolts are known to seize. Usually they will use a welding torch to heat the bolts and loosen them or burn them off. at the very least i would say you need a good penetrating fluid and something to cut the bolts off if needed, a grinder of some sort. you might be better off having a mechanic do the job for you. or buy the parts yourself and have a mechanic do it for you if its cheaper. if not your also probably going to need some bolts. be careful not to damage the catalytic converter or its flange. let us know how it goes or if you have any other questions
hi Max. yeah thats the one. except that one only has the flange on one end. he'll need to either weld a flange on that pipe or have to cut the flange from the other. he mentioned wanting to do the job himself. not sure he has access to a welder?
Sorry for not providing much information regarding the issue. Yes the part you located is right. When I clog the exhaust with something, I can hear the hiss coming from the flex pipe. I think I have two ways to go.
1) I can cut off the flex pipe part, then put a new flex pipe there and by using muffler cement and clamps, I can fix the issue for now.
2) The other way is to buy the part(s) (Max provided the picture and you suggested two gaskets to go with it) and get it installed in somewhere.
I think the 2nd option is the way to go. However, I was wondering instead of the gaskets provided in the link, can I use some kind of high temperature gasket maker?
I am going to try to use a ratchet myself and see if I can change the part. If not I will take it to a mechanic with parts. The only issue right now is the gaskets which are I assume dealer specific. Am I right?
Thank you for all your help and I will give updates on the issue.
Purchase the appropriate OE style gaskets to maintain the correct contact and seal.
You may be able to install a new pipe section yourself, but the long fitted fasteners are often a chore to remove and require torch heating.
Any exhaust "patch" job is a waste of time IMO, ESPECIALLY on a moving "flex" joint. Get the correct parts and HAVE them installed, is my suggestion.
It also appears that the rear of the pipe portion of the flex section is a clamped "slip-in" joint (and also difficult extremely to uncouple without the correct tools), so only a single gasket is needed at the front flange.
