Im about to boost my 94ls that is in my 88 crx and im going to need a downpipe. What size downpipe should i go with 3in. or 2.5 in. and why. And where can i find a down pipe made for my setup, am i going to have to make my own. And does the piping have to be mandrel bent. thanks.

 

I would reccomend using 3 inch mandrel piping if you can fit it. If not then go with 2.5 inch mandrel. The larger diameter allows the exhaust to flow out of the turbo easirer with less back pressure, which promotes faster spool up.

EDIT: You should be able to get the mandrel U-bends form summit or jegs for pretty cheap.

 

should i use mandrel bends for the fmic piping too.

Only way to go.

 

remember to get something suitable for extreme heat, thick stuff. Ive known many people who have had to reweld many times

GOOD LUCK
