This converter works perfect. I just got a 3.99 adapter for each end and clamped it all together. Truck runs like new again and all my CEL's are GONE! With discount codes I got it all under $100!

Good luck
The big warning sign with this is 'Universal Fit.' I'm sure this would be an OK product if you were building a custom exhaust. If you are trying to use this on a factory car/exhaust, measure three times then hope you have good luck and are ready to make mods to use it. Do not expect to just bolt this in place and go.

Universal? No.
Staff Reviewer -
This part does not fit in the space available on a Hyundai 02 Elantra at all. No amount of modification would help either. Simply the piece does not fit in the space of current catalytic converter.
Bottom Line No, I would not recommend to a friend

Inexpensive quality replacement.
Verified Buyer -
Good product but very little room for error when cutting off old catalytic converter and matching up to new.
Great Deal!
