i have searched and i know someone out there has my set up and knows the answer!

i have a 98 gsr with greddy turbo kit, the downpipe goes to the stock location, so it works with stock cat and stock exhaust.

i have a Thermal 3" catback which the B-pipe is much shorter (for fittment on different teg models). my question is to those of you who have a greddy kit and thermal exhaust, how long did you have to get your test pipe to be?

i had one made ~17.5 in (stock length) and it is way too short.

i would rather have a custom one made (SS, flex, TIG weld, etc..) than going to a exhaust shop and having them chop and add to my current test pipe.

whats the test pipe length!?! thanks

 

i know someone knows the exact answer!!

 

?????????

need help

 

this is pretty hard to believe

 

The only answer to this is to crawl under the car with a tape measure and do some measuring.

 

i just dont want to end up being off a little and have it not work.

will the flex section allow for more or less length if necessary?

 

Not really - maybe 1/4" at most. Its around 19" on my 00 GSR.
