i did the filter first and really need and want my exhaust now but i have to start fixing this bad boy now before i can have anymore fun parts

im not sure which is the way to go i got the filter first as i've always known of people who got filters but never did any exhaust work and i did notice top end breathing improvement....but i dont know that getting the exhaust wouldnt have been a better way to go

but case is to get filter and exhaust at same time for best results
