i was looking through the ads for a S4 rb presillencers, but S4 ones cost more than S5's, since they dont have the tube.

also will a GSL-SE presillencer work with the stock mufflers and a rb s4 streetable header?

back to the tube, could you just simply install a s5 one and tap threads somewhere in the exhaust for a fuel nipple with a matching diameter of the tube?

or better yet use a brake bleeder nipple

 

You're going to inject fuel into your exhaust? This should be entertaining as hell...

IN for videos, and scans of insurance claim and newspaper writeup.

 

so you drive a GSL SE? see the first gen forum, not the 2nd gen, and as far as presilencers, get your cats out and insert a open tube(test pipe) and go from there, as along as you dont have emissions testing...

 

I'm going to assume he meant air to open the 5/6th ports. If not... +1 to the quoted post.

 

Ya i meant to say use air to open the aux ports lol

And its for a S4, not a GSL-SE, i was just wondering if a GSL-SE presillencer would fit a S4 since its cheaper. But it dont matter no more, all my aux port problems are solved.

i never got a good look at my exhaust. The previous owner fabricated a custom exhaust

he made a 2.5" straight medrell bent pipe replacing the first and second converters, just leaving the last converter with the aux pipe. And a 3" to 2.5" Y pipe.

A totally sweet surprise! it just saved me from buying a S4 presilencer!, il just buy a RB streetable header and shorten the straight pipe and weld a flange. Another bonus was that even with one converter it was very quite!

lol this also explains why it barely squeaked by aircare, o well at least its still aircare legal.

All I see is a fairly pieced-together exhaust with lots of different sections of pipe? What are we supposed to be seeing here?
