whats the diffrence between turbo and non tubo exhaust

[GreddyEclipse]

ok what exactly is the diffrence i emailed greddy and they wont reply and i am going to go with a bolt on turbo for my car but if i put on a turbo exhaust will it hurt my car or is it going to be fine same with cold air intake. It might be the dumbest question but please help

[EclipseRST]

what are you doin to support the turbo? how much boost will you be running? either run a 3" custom made exhaust or get a 3" NT exhaust system and have a DP made... it all depends on what you plan on doing to the car, if you not goin to run anymore than 8psi then go with the 2 1/2" exhaust... let us know more about what your plans are so we can help you more.

I have a GS but i am going to put on a star perfance stage 1 turbo but i have to wait a month to order it and didnt know if i ordered a greddy turbo exhaust for a eclipse and if it would work fine or not. Sorry I am kinda new to this and i try to research and i found out u guys help out the best thanks. Thats the same way with the cold air intake to i didn't know if i had to have the turbo on it first or not.

ok exhaust is exhaust some what if u plan on putting a kit on your car then i would say no less than 2 1/2 pipes i would just go with 3 have u thought about the Apexi N1 they make it for the turbo and non turbo models and its a dam good set up. As for the cold air your star kit will come with intake piping im pretty sure they dont make cold air for the star kit if u where GST GSX then they make cold air so if u get cold air now it will be while u are NA once turbo goes on the cold air will not fit so i would say save your money also have u looked at www.hahnracecraft.com they make the best turbo kits for the NA eclipses cheaper to and u can upgrade threw them with the set up u have i like the T3T4 with the star but the hahn kits are nice and proven and they help u alot they worked with me like crazy when i turboed my GS i have the stage 2 kit with a upgraded fuel system for 12 psi along with the internals if u did order the other greddy exhaust it will be fine too check that site out and see what u think u can also call them and tell them what u are looking for and they will tell u what u need 2 get. hope this helped u out a little

Some punctuation is always nice, hard as hell to read a paragraph sentence and try to figure out where the sentences end.

The difference between turbo and non-turbo exhaust is the downpipe instead of headers, and size usually -- non-turbo are smaller diameter. You can salvage a whole system minus before-cat (downpipe) when you switch to turbo, but your car may not run at peak performance running a 3 inch exhaust now, and you may not even run enough boost later to warrant it over a 2.5. 2.5 inch seems to me like it would be OK later, and is definately fine now, you will just buy a downpipe unless one comes with that kit. good luck.
