if I were to buy a 5" exhuast system, is it normal for it to be a 5" down pipe? Or do they give you a reducer to hook into the small factor down pipe? If they come with the 5" down pipe is the any issue I need to be aware of in hooking it up to my factory turbo or future twins?

 

its usually a 4"dp then 5" the rest of the way. unless you have a s400 turbo, those use 5" dp's

 

Where are you going to get your 5" exhaust? I'm looking as well. thanks.

 

i bought mine off ebay for like 300 no welding.

 

power by pool is where I am gunna get it from, it's only like $370 for 5" stright pipe from turbo back

 

modsfortrucks.com is where i got mine from for 300 shipped it didnt have a muffler
