Question: L98 1991 Resonator elimination? front Y ?

[stratinik]

I found a Front Y exhasut on Ecklers that goes from the exhasut manifolds to the cat converter and elimnates the two front resonators .... has anyone done this? will it be too loud inside? what do I do with the 02 sensors? after the cat converter I want to go witht he Bolra exhaust....

opinions, experiences

Those are not resonators. They are small catylitic converters called "pup cats" which were used on some of the last model years of L98s to get the car to pass Federal emissions certification.

You can gain some performance by going "pupless" and their removal will not affect the car's passing a state emissions test.

The exhaust will be slightly louder once you take them off.

Thanks Hib.... can I ask if you know what I do with the 02 sensors? will eliminating them affect SES or dummy dahs lights?

I had the same setup on my 86. If the O2 sensors are in the exhaust before the "pup cats" than nothing is needed. Although, they probably do create additional heat in the exhaust, you may find that you need to run a heated O2 sensor. Probably not the case though.
