sup all! im trying to put a 3 inch muffler with 3 inch piping for my 2000 civic si. almost every shop is telling me it wont fit my civic. either its too low to the ground or they say its going to mess up my motor. not sure what they mean though by messing up my motor. so can anyone tell me if they have done this to their civic or integra?? thanks!

dont go too big, even though it is turbo, biggar is not better. it should be 10% larger than the diameter of the exhaust turbine outlet. usually for a car 200-300hp you should stay in the range of 2.25 to 2.5. usually 2.5 is the biggest you wanna go.
3 inch all the way, Why do you think Thermal turbo catbacks make the power they do? In an turbo application you want the exhaust gases to have unrestricted flow, it will also help spool the turbo quicker. I have 3inch on my civic and I have never had any problems in almost 4 years! I am planning on doing the exhaust on the Teg this spring and you can bet it will be the thermal setup.
If you are running a t3/t4 or bigger turbo 3 in is NOT to big. I spoke with tony who works at Jotech. If you don't know who he is lets just say he built jotechs 8 SEC honda. He said 3 in is perfect!!!it is not to big.
go for 3" piping, it'll give you much much better power than a 2.5 or 2.25 rig will. It'll fit fine too. I think those dudes at the shops have been inhaling too many fumes.
i will scan in direct quotes from corkey bell, one of the greatest men in turbocharger history. i took all thoes stats from his book on turbochargers. the same man that single handedly developed a turbo kit for the nsx. are you telling me he is wrong. i think you better research before you post bs.

Its common sense man, If you are going forced induction, a Bigger exhaust IS what you need. If a lot of air is going in, It has to come out freely with out restrictions. When going N/A, you don't need that big of an exhaust due to the engine "asking" for air vices "Pushing" air like in a Forced Induction system.

smallar diameters will create more heat energy, and more heat energy creates more flow. after all, the turbo is run party by heat energy and partly by exhaust gasses.
and once again, this isn't my personal findings, im just sharing what a turbo god has put out for people to grasp the concept that maybe some kid on his computer arguing on superhonda that corkey bell is out to lunch should think before he posts.

Is Corkey your only source for info? You need to search for other sources and get other opinions on the matter... Chances are most of them will tell you to go bigger, not too big, but bigger. Bro, I know what Im talking about. I don't care what Corkey said or wrote, I'm talking from personal and proffesional experience.

i dont think i need another source, and i sure as hell dont need "opinions" this is not an opinionated question by any means. some 12 year old kid can have an opinion, but corkey bell has accurate info.
im not even gonna waste my time arguing with you, ill just let someone else set you straight.
rickyvtec i think my sig says it all. i got only a drag kit running on stock piping. nothing else except colder spark plugs. hehe well i just read a great link on the civic si forum. i think it will answer both you and low did's questions. check it out!anyone with a 3 inch muffler with 3 inch piping?
i think im gonna go with 3 inch. only thing i need now is a shop that knows what they are doing and help me install my hks muffler and 3 inch cat. anyone from the bay area know of a good shop?? thanks!

yes, the turbo creates backpressure, and it wont harm you engine to run 3", but the best size for turbo is stated, anything more is overkill.
i still stand by the fact that you shouldn't run biggar than 2.5"
