I just picked up an 85GSL SE and am debating whether to put the Racing beat cat removal pipe or the pre silencer.

So far I have the headers, and CB from Racing Beat but don't know which one I will get. Does anyone have the setup i'm looking into? Headers, Cat removal, CB, and also headers, pre silencer, CB?

Will the straight pipe be too loud? What would be the power differences between each?

i had this setup!!!...i first ran the catpipe with the RB muffler very quite but nice on the top end with a low deep idle......

YOU CANNOT RUN THE CATPIPE AND HEADERS ( < sorry for that i just made that mistake and dont want you too either... the catpipe is to be run with the stock manifold not the headers it is a either or type deal.. if you use the headers you can use the presielncer but if you are also using the RB muffler with the headers and with straight pipe to the muffler, it will still be the same noise level as the worn out stock muffler....mine was acully louder with stock manifold cats and stock muffler compared to the new RB muffler with headers and custom made straight threw middle section pipe.......
