Sup guys i have a few questions that have been on my mind about my custom cat-back. Tubing will be 2.25 .....I have my muffler.
2004 Sunfire 2.2 Ecotec Coupe

First off..i am about to purchase the Pacesetter Polished Armor Coat Header from TTR...since I don't have any motor mounts I am going to get a flex pipe...I just don't know where and neither the less which one I should get.....I searched in ebay and found some but I have no idea which one to get.....As for the installation of the header I am going to get it done by a mechanic..what is the most I should pay to get it done? Any suggestions? As for the bolts do I need new ones or can i use the same stock ones......And what are the possibilities of any bolts breaking?

As for the Catalytic converter I've been searching for awhile and seems to me everyone pretty much uses this on on our cars MAGNAFLOW Catalytic Converter 2.25" w/ O2 Sensor #94035 . Correct?

Also with the resonator....I am going for a low deep sound.....and of course i've searched on here for awhile and found out the longer the resonator is the better.....my question is is this resonator long enough and will fit perfectly with my catalytic converter in length wise...... http://store.summitracing.com/partdetail.asp?autofilter=1&part=WLK%2D24205&N=700+400358+302015+115&autoview=sku ??

I think thats about it......Thanks
