i looked for this but couldnt find the exact answer. Does anyone run a straight thyrough exhaust from turbo to one muffler to tailpipe, no 2nd muffler, and no cat? Im thinking this would be more free flowing, and ME doesnt require emissions, and it also would be a throatier sound? Any advice?

 

if you have no emissions, then do it. mine has a high flow cat, resonator, and muffler. it is fairly quite, and has a deeper note.

 

I had it, then I got rid of it. To loud and it got annoying after awhile.

 

i have to replace my rear muffler and axel pipe, and possibly my front muffler. Im thinking of just running a straight pipe from front muffler if thats the cheapest. ANy other ideas? Turbo straight to muffler, then straight to end? No 2nd muffler or cat?

 

That would be nice. do it.

 

is it gonna cause a problem with back pressure for the turbo if i did turbo>straight pipe>muffler>straight pipe?

 

no... you dont want back pressure on the turbine.
your turbo will thank you.

 

alright im a noob to volvos and a n00b to turbos soo good to know

 

are you doing the work yourself? or having a shop do it?

this is a good time to increase the diameter for better flow... if anything, I would start out with using 2.5" piping. this is a decent size, and is better then stock, which I believe is 2 1/4". if you plan to go further with the car, like bigger turbo, or tune it. 3" is what you want.

 

ill be doing the work myself i can do all clamps, i dont have a welder. Is that possible? And im thinking of going up to 2.5" if ican. Can i just cut and fit and clamp it all togehter?

 

you can. just make sure you check for leaks. the stock downpipe is 2.5" so if you cut up a little past the cat, it will bolt right up with the new clamps.

 

solidd

 

i would recommend going to a shop. I had my whole exhaust done turbo back for 150 in 3 inch tubing.

 

adub, was that with a new cat and mufflers? Or what did you have on it? Im bring it to a shop on friday to get the fluids changed, timing belt checked, and exhaust, maybe brakes, gotta see how long this will car before any work goes in it tho.

 

That was with a glass pack muffler no cat.

 

you can solder before you place the clamp....buy a tub of everflux and plumbers solder, a mapp torch

put everflux on clean sanded ends with a small brush...just a light coat all around
fit together
apply flame to bottom of pipe connection
see the flux bubble and at the same time apply the solder on the sides
move flame to side and apply to bottom
same goes for the top of pipe

place clamp after...done

 

alright, im taking it to a shop tomorrow for other questions and maitnance, so ill see how much he charges me, and that will decide it
