Yep! Fall into 3 main categories;
1.) As per OE but without cat (ie; wastegate blanking plate still there
2.) No cat and enlarged turbo mating to allow wastegate gases easier exit
3.) Twin dump - separate pipes for exhaust and wastegate gases of varying lengths
2 or 3 are better then 1 from a design viewpoint - but on an otherwise standard car just removing the cat will give the biggest gains anyway.
