Borla S-Type rattles


Recommended Posts

I have the 2020 AT4  6.2 with the borla s-type exhaust.  Absolutely love it except it rattles at lower RPMs on the stock exhaust tips.  Looking for suggestions on eliminating this nuisance (I have already re-torqued the mounts).

When I installed my cat-back ( GM performance, AKA borla) I had to adjust the final section of the pipe a little in and out and twisting until I got the pipe to hold right in the center of the tip so it wouldn't rattle. You might try to loosen that last section of pipe and adjust it a little.

Its all in the adjustment of the tailpipe section and possible mid pipe as stated above  I have the same exhaust with no rattles, and it is possibly the best sounding exhaust I have ever heard.

I’ll try and adjust.  I agree that this is the best sounding exhaust I’ve ever had, which include magnaflow and flowmaster.
