I have a friend that is tehcnically giving me his nismo exhuast with the trade of my stock exhuast. The one problem is that his catalytic converter is pretty scrapped up bad. I dont know much about any of that stuff. can someone fill me in and how how much it would cost to repair it?

thanks

 

Why trade converters. Keep the ones that you have.

 

shake it a little...if u hear stuff rattling inside it...well u might not pass emissions....

 

Thanks for thei info guys. so i guess i can switch the exhuast w/o switching converter. Im a newb at this, i know. I'm just making sure i'm not getting screwed up. thanks

 

Its all good. This forum is filled with photos under the car. Search and study. You will figure out what goes where.

 

The part you're thinking is scvraped up, then, may not be the cat; you may be thinking of the braided flex-pipe sections of the Y-pipe of the exhaust. Some of them get scraped up pretty bad on lowered cars, but the braided part is just a covering over the actual flex-pipe, so it'll be fine, if that's what it is.

 

here is the picture i have of the catalytic converter if i'm not mistaken.

 

That's The Flex Pipe. Not The Catalytic Converter

 

There are two catalytic converters, and the Nismo exhaust does not include the cats. What are you talking about.

 

LMFAO
that is part of the Y-pipe, genius. Unless there is a leak, you will be fine.

 

I just posted a photo of a catalytic converter above. How about you stay after school!

 

This is a catalytic converter. Please look at the stuff under your car.

 

mine is scraped like that as well. how much is a new nismo flex pipe? will this cause a rasp in the exhaust? i have had my exhaust for like 3 yrs now and the first 6 months or so i never really heard any rasp and now i do. is this the reason possibly or is it possible my R/T high flow cats need to be replaced? sorry to thread jack just need a quick question answered

 

Flex pipe will endure a lot of abuse. Its designed to do so. If it is not leaking, leave it alone.

 

You can't just buy a 'nismo' flex pipe. You can either get it fixed at an exhaust shop, or get a new y-pipe.

 

sorry thats what i meant how much is a new nismo y pipe
