Ok so i just had my birthday and i want to spend some money on performance parts for my car, i.e. full exhaust set up. I've pretty much decided on getting a cat back from the mandrel bent exhaust site, aluminized 2.5 inch, magnaflow muffler with an added in 18'' magnaflow resonator. Now for the header and dp, im unsure what to do. I was thinking about getting the zzp midlength header and dp combo or getting the shorty header and downpipe seperately. Is there any advantage to either one of these? I'd be getting a 2.5'' dp with no cat, what size header should i get? im a noob when it comes to this so any help is appreciated!

Why catless? I think they sound shitty without one and you're looking at maybe a 3whp difference, but that's my opinion.

I'd say get a quality head and dp (if you KNOW you aren't going to go F/I, otherwise just a dp), highflow cat (ZZP sells these with their DP) and a quality catback and get a tune.

 

Alright... Well like I said I've already picked out the catback I want. I just wanted to know the diference between getting the midlength or the shorty header and dp
