I'm pretty sure it's not, because the RMM downpipe is 3" and is considered a huge upgrade from the stocker.

Well I am not sure how my HKS 4" Ti is going to fit then.

It should come with an adapter. If you don't have it you can buy it from MVP or one of the other vendors.

^ bingo...

also use the search button... there is not such thing as a STOCK DOWNPIPE... The USDM MKIV TT Supra came with cats not a Stock downpipe... all downpipes are aftermarket.
