Well i started making the exhaust a couple of weeks ago, i wanted to keep it looking sort of oem just stainless and electro polished went for a 2.5" since it pretty close to the original size and i fellt going to 3" would just a waist.
What i needed was the catalytic converted and everything behind that, really didn't feel like buying a cat so i made my own;
Sorry some of the pictures are shackey and in allot of them the pipes are dirty had to test drive the car a bit

its there just so the car can get registerd they dont know whats on the inside but since i had the opportunity i decided it would be nice to put in a net just to deaden some sound

Had to make my own Y-pipe made it out of 45° bends its 2.5"in 2x2.5" out

then becouse of the fkn holydays i couldnt get more bends so i tought it would be a good time to practice my welding and makeing bends

welded two T-clamp fitting after the y pipe

When i got it back a fitted a 2" net cylinder with some larger holes and wool on the outer side and put that into the "silencer"

The silencer is iirc 4.5" pipe 2.5" in and 2x 2.5" out thought about doing 2x2" out and honesly it would have bin ALOT easyer to make but didnt fit the look as nice from the back i think the 2x2.5" pipe fill up the holes in the bumper alot better
I also thought of makeing it 3inch out but it didnt fit the look i was going for

(btw there is about 4cm space from the two pipes to the cylinder)

Ok now for some technical info
The four pipes you see at the back of the car are cut with 11° degree angle ( I tested ALOT of angles) and on each side they outer pipe is 1cm shorter than the inner pipe (alot of thought went into this as well ) now they kind of flow with the angle of the bumper

btw for some reason the car only smokes from the right pipe when idling, I think its because its shorted distance for the exhaust to travel

For now the gas tank will stay in the trunk.... reason time and money
