Again as I responded in your other post please use the search feature in the upper options bar, there are many great threads about mufflers, exhaust systems and anything of the like.

i did search, and nothing pertained to my question, i looked through the forum, im not new to this forum stuff, but the general consensus is that the 1.1 didnt sound very good with mufflers i just wanted someones oppinion on the matter, as for my other thread sry bout that, i was meening to ask about more techincal books, with diagrams and such, for the gt, those others were basicaly like general knowledge books when i searched amazon

The main stumbling block is that there are not many 1.1 litre motors about so very few people have experience of exhaust systems for them.
I have a 1.1 SR motor in a Kadett Rallye and ended up with the OEM original Opel rear muffler - guessing that Opel did a bit of R&D on the right sound!
Generally - keep the pipe size smaller at around 1 5/8" instead of the 2" for the bigger motor and look a mufflers made for smaller UK imports like Minis or Sprites/ MG Midgets. On GTs the standard 1.9 system will be big enough for the 1.1 back past the 1.1 down pipes, I should think?

As for technical books on the 1.1 GT about the only thing available will be thw 1969 Kadett & GT Service Manual - and you will have to find one of them on EBay .... they have a browny redish cover with those words printed in white on the cover.

I think you're right; everything from the muffler back is the same on the 1100 and 1900 GT.

The 1970 Kadett & GT manual with the black cover also contains the 1100 GT information and specs.

I believe I a used 1.1 muffler stock on my shelves for a GT. The inlet and outlet were smaller than the 1.9 one I put on. This is the muffler under the floorboards, not the rear muffler(resonator) at the rear of the GT. It can be yours for $5 + shipping if you are interested.

Let me know.

thanks everyone, ill take a look around the internet, so would a 1' 5/8" pipe be the best choice for exhaust tubeing

[jordan]

I have a spare ansa muffler with I think 1 5/8" inlet/outlets, but I will check on the sizes

[lilgecko96]

I looked around the internet and all I could find were some lil mufflers for peugeots, and one for a ford ka, but I don't want it to have the "import sound" like my other cars, how about if I take the rear resonator completely off, I'm assuming it will be a lil louder, but does it make it sound like crap? if there's any muffler out there that I missed let me know please, it would be much appreciated.

This is what came on the Kadett and GT 1.1 engines for exaust, the GT had a 'resonator' the Kadett only had a tail pipe. The O.D. of the exhaust pipe is 1 5/8". As I have both the exhaust pipe, muffler, and the over axle piece, NOS all with the Opel Numbers (paper tags) still on them.

i dont need to buy a new oem one, my car only has 23,000 miles on it

[Killer Texas GT]

Ok, you have the GT with a 1.1, correct? Take the mufller off leave the resonator in place. This will not give you the Rice burner sound but more of muscle car sound and a lot louder. To test go to a parts store get a short section of flex pipe remove you muffler and install the flex pipe ($5.00) to find out if that is the sound you are after.

[lilgecko96]

yah its a 1.1, ill try that this weekend when i go home, thanks for the help

[asdasc]
