4" or 5" exhaust
 

Would y'all recommend 4 or 5 in exhaust? Where is the best place to find a straight exhaust system? And what about a down pipe? 3 or 3.5" downpipe? I don't want to do any cutting on my firewall and I would like to get a system that was easy to install. Or would it be easier to just put a downpipe on on let a muffler shop put an exhaust on there?

Thanks

MBRP or Diamond Eye kit. 3" down pipe, 4" exhaust 5" tip. thats what most people do. find a porta power and use that on the DP, you just have to smath it back, no biggy, we all do it. its up to you on the exhaust tho, you can do it yourself or the shop can, depends if you want to pay someone or not

Thanks Simpson. Where is the best place to order a tw chip and what tunes would you recommend?
