Ight i have great issues with searches i cna never come up with what im looking for, so if its there already i dont want to here a lot of fussin, I have a '94 gsr and just need to know if a type-r header will just bolt on to the stock cat or if i need to change rest of my exhaust as well.

 

the usdm type r header will bolt up to your head and fit your stock cat, but modification may be needed since the length of the a-pipe (the lower portion of the header) is slightly different on type r's than on 94-99 gsr's.

 

yes it will bolt rite on, but remember that jdm itr collector is 2.5 while the usdm cat inlet is 2.38 and the hole where u put bolts wont line up... so just get a aftermarket or jdm itr cat too..

USDM ITR exhaust piping is not 2.36 (60mm), if my memory serves it is closer to 2.25 with a couple of 2 inch bottlenecks.

 

i have a usdm ITR header for sale if anyone is interested
