So i have the CTI header and 3" DP with a 2.5 exit to connect to my 2.5 custom magnaflow. The exhaust shop used my stock 2.5 flange for the catback, but for some reason, they have replaced the gasket between the dp and catback flange twice and its still leaking... Its like the flanges wont bolt up together right.. Is there anything i can do to fix this im tired of hearing the leak right under me

 

the flanges are more than likely warped or slightly different styles that look similar

you can buy a 3 bolt or v-band flange and have any shop weld it on

 

That is exactly what I had to do because I kept eating up that gasket.

 

i use the permatex red exhaust flange sealer it works 100% all the time on my CTI Nooooo problem

 

what is it like a high temp silicone?

 

Yes stock #27BR Sensor safe Red Hi-temp gasket maker from Permatex, "made for the professionals" (lol)

 

where can i find something like that? do i have to get it online?
