I finally got my exhaust in the mail. I got flomaster mufflers and tailpipes 2.25' all around. So my question is if i go with 2.25 piping from the header to the mufflers is that gonna be too much flow, should i go 2.00" to the mufflers? any ideas

 

are you making it dual with a Y pipe from the header? if so let me know what y pipe you used, and what exhaust system, as in which tail pipes from which kit and such. im interested in how this will turn out.

 

I got this pacakge from ebay for 200, all brand new. it came with 40 seires mufflers polished tailpipes that go over the axle all bran spakin new. I havent botherd to figure out what size piping before i do. i plan on using single exhaust from the header to the catalytic and then y pipe it off to the duals

 

is it the 87(or 78, cant remember) to 93 GT american thunder, force II, LX american thunder, LX force II,...??

 

its the 87-93 lx american thunder

 

cool, where did you get your y pipe? do you know if itll fit correctly?

 

I didnt get a y pipe yet, i wanna figure out if 2.25' is gonna be too much flow for the exhaust or if i should down size to 2.0' pipeing

 

2.25 should be plenty. the header itself causes enough backpressure, you should be fine.

 

Thanks for the replys. what after market mods do you have done to your car. And i found a y pipe from magnaflow 2.25 inlet and 2.25 outlet,10' long for 30$ free ship also

 

will it line up correctly? can i get a link to that, please?

no aftermarket mods done to my car, i customized myself an intake to the fenderwell with pvc, but that was mainly for looks to get rid of the nasty air box. try racingwalsh.com
