Sorry... mis-type. 400+ HP for ProChamber H-Pipe. Looking for a mid-pipe and new shorty header set up as well.

 

I dont know where you read that. The normal prochamber is 2.5" and is rated for whatever HP you want to have. I have a mac h-pipe and my best friend has a prochamber. Both of them are just plain bolt on GTs and both sound amazing.

 

I have a prochamber and would suggest looking into it. It really rocks!

 

http://www.proficientperformance.com...&Store_Code=PP - somthing like that? alot of people were saying to make sure you get ceramic coating, or is that just on the headers?

 

a shop will not install and or h pipe or a ctted on for that matter because govermnet regulations from the EPA say u can not mess with working converters.

at lesat here in IL this is how it is.

 

i already called a shop that said they would install a catted hpipe for 110, im in cali.

 

im looking into a h-pipe and was going to go no cat's is this a good idea with flomaster american thunder series exuast and what will i need to do for the o2 sensers im still unclear on that? and anyone know the cheapiest place to order one cause i think shipping will suck

 

well i went to Exhaust works here in Naperville, IL and they said they will only instal cat back systems so i guess i have to find a good performace shop around here. u guys know any?
