Low End Torque after Magnaflow Cat-back installed

Post by SilverExpress »

Has anyone felt a decrease in low end torque after installing the magnaflow catback? Do you find yourself giving it more gas to keep up with stop and go traffic?

Well Jose, I wish I brought the Vibe to the meet. I could have shown how it sounded and everything. But I didn't have access to it at the time. And to answer your question, there seems to be some torque there, but I can't really tell until I drive it without the exhaust when I take it off to put it on Shagginwagin's.Inder

I actually felt a significant torque increase. The pedal just felt more responsive. I have a 2zz engine though. I guess it may affect your 1zz differently.You may want to reset your ECU and try again.

He doesn't have it yet. But Silver, I would recommend running this setup on your car. JP/Trial Header, JP midpipe, and a Borla exhaust. That would definitely set your car off nicely.Inder

I have an Ingen CAI and a full Magnaflow catback. I have no problems and mines a base vibe.
