Hi all, I have a 2009 135i with stock cat back exhaust. I already blew out the rear cats with 2Step and NLS...and blew a turbo...so now I'm going to be throwing in a VM/ACF too mount 6466 and was wondering what I should do for my exhaust. I will be running in the mid 500whp range for a few months to maybe a year until I can afford to get port injection. So, as you can see, I am kinda tight on money. With that in mind, do you think that just doing a rear cat and muffler delete and welding in some pipes in place will be good enough? I'm probably gonna put in two vibrant resonators as well to keep it toned down. Any suggestions or thoughts? Furthermore, I'm wondering about doing cutouts as well...anyone got them and if so, what does your setup look like? Thanks!
