Anyone know what size the opening from the headers is? Thats the same as the exit for the presilencer right? Thanks in advance.

 

Anyone?hmmm..?

Now I know many of you guys have the RB headers &/or presilencer...what size are the piping?

86-91

exhaust components.

 

I looked there, it does not say the dimensions, like if I was to attach a pipe to the header what diameter? Someone has to know. Thanks.

 

Use 2.5" pipe and the 2.5" presilencer flanges they sell.

 

Thanks alot man.

 

No problem. Are you trying to make a pipe to go from the header to the cat back? If so it's going to be VERY loud.

 

I am going to make a pipe too, but it will be out of a reasonator pipe so it will help to reduce the noise some, and I still have the stock cat-back so that will help to reduce the sound as well.

 

How are you planning on making that? I want to get the headers but don't have the $$$ to get the presilencer at the same time so I want to just use a straight pipe for now. How much does the presilencer help anyways? Thanks.

 

The presilencer really helps to keep the noise levels down. I've heard a car with headers and a straight pipe and it was MUCH louder.

 

Hmmm....(thinkin)...have any of you guys heard a 7 with holes in the mufflers? Mine is soooo damn loud I can't even begin to imagine it louder, lol. Even with the headers. Maybe a different sound, but not neccesarily louder. I just can't c it. I set off car alarms, lol. No kiddin.

 

I have an exhaust leak at my downpipe and an open air wastegate. THat can get quite loud.
