Catted header with stock exhaust
 

anyone know of any issues installing a ft86 speedfactory catted headers but keeping the stock exhaust. will it fit? negative performance issues? figure on getting a tune

I have that set up now. No issues at all. Fits perfect. There's maybe a tiny difference in performance without a tune.

I just added the OFT a few weeks ago. The performance and overall driveability is much better. Waiting on a cat back now so I can hear it a bit more.

Yes it will fit fine. Sure, you can tune it but gains will be minimal.

thanks . good to here
