You may get a few hp bumps. but I don't think it will be like remove primary cats.
You will have a nice sound with that setup. Nothing wrong with modding on a budget :-) Hope all works out for ya
Sounds good. Would I not pass a sniff test for emissions? Illinois currently only requires OBD hook up to see that all the sensors are ready / clear of faults.
Also, last question:
Know what sounds like a reasonable price for the 2ndary cat delete? I've been getting a few quotes. All seem relatively high.
Thanks for all the help. This thread is the epitome of useful.
