Does anyone know if i can use a SR or another brand of downpipe for a s13 RB20?Yes i do know there is McKinneys, but i dont know if they are the same size as a regular SR one. I 'm trying to just figure out and would like any help possible.If not then i'll resort to buying the Mckinneys.thankyou

i bought that downpipe and the overall quality of that product is terrible. i had to cut both flanges off and reposition them, plus they welded way to close to the bolt holes so you couldn't get a bolt/nut to sit flush.

i was extremely disappointed

Get an sr20 downpipe and cut the flange and rotate it.

The SR one sounds like a good ideaAlso another problem i heard is that sonetimes it depends on the motor mounts on how the dp will line upI have the McKinneys basic $300 mount kit thanks

Not a big deal, get the flange rotated and if it's short, extend it, if its long cut it and reweld. lol

Syko performance makes a turbo outlet that you can use a SR downpipe with. downside is it costs 200 bucks

This isnt my pic but i found this pic around the forum from someone else. but this is the topspeed downpipe and it fits like a charm, just dont go slamming your car. im usin this exact one. I got my dp through SP Engineering but i have also seen these go on ebay sometimes.

rb-performance.net was in the process of making a custom downpipe last time i saw them trying to fab one up. i dont know if they are finished making it yet.
