Just wondering is going for 2.25" exhaust piping on a B18C civic (euro 1.8vti) with a K&N to big if ur planning to keep the car near enough stock. Was gonna get supersprint exhaust but this uses standard size piping so i can't see how it will produce a big improvement. At the moment thinking about getting a magnaflow universal backbox with custom 2.25 piping. Also wondering how would 2.25 piping connect to the cat which is standard size and if it can connect does this not create a bottleneck having a standard manifold and cat but larger cat back piping hencing making it pointless get 2.25" piping over stock

it makes the worlds difference for me, but i also had to put a OBX header on my car(the flange was way too small) i have a 92 CX so everything on or around my engine is TINY. with the header tho it still only costed $450. thats a whole lot cheaper that most of those nice catbacks and this prolly works better.

thanks for the advise, thinking about the dc sports or obx header in that case. Problem with having a euro only civic is i don't know exactly which header or cat i should get as these don't come for my car. If i get ones for a teg gsr or type r hopefully they should fit.
