Exhaust Iteration No4 ish (Side exit )
Discussion
So in the time I’ve had the car I’ve had a selection of different exhaust systems and styles on the car . First was with cats into a y pipe single to the back, well that wouldn’t do , so some on here may remember I made a full straight through stainless twin 2.5 system with xpipe. It worked but was hideous loud and too raspy for my ears. Added headers which improved the sound and some centre silencers
( magnaflow) which did nothing. It was still to loud for most track days being over 100db
Recently I’ve had a mild steel capa system with double H link pipe.
This sounded awesome but hit the body underneath a lot and has now cracked where it went into the centre silencers .
So. It was always in my head to do a side exit, but couldn’t deal with it stupid loud , as these days you are to limited to which days you can do if your car is over 100db.
I did find a company in the states doing a nice side exit system for 700 dollars and it looks good but shipping was $1700 !! Well that’s just stupid so I ‘took inspiration from it’ It’s a spintech system.
First Job was to add some flexies to my link pipes, not really necessary, but helps stop cracking as this will be a mild steel system,I think mild seems to absorb a lot of tinnyness, and it seems crazy to make it from stainless when the body is normal steel!!
Then join into the HH mid from the capa system .
Now set about silencers, with what I guess/estimate to be enough to quieten it without being restrictive.
The inlet and outlet have a second plate for strength, seems exhausts always snap where pipes join silencers. This should stop that.

I’m doing the measuring and offering up at home and the noisy cutting and welding at work, for the sake of my neighbours and I have a wooden garage at home(not ideal for welding! ) ,which makes for slow going, but it’s fitting up nice
Just got the hangers and the oval exits to do now , which will take a good bit of tooing and froing to get the exit just below the sill , like so ..
Opinion’s please as to whether to leave like the above or slash cut in line with the sill ?
Should be ready for a fire up early next week , with DB meter app ready . I’m awaiting a cube shifter as well ,as weirdly the stock one is letting oil out ! so the gearbox crossmember is lowered, making it difficult to move the rear axle stands to make room .

I didnt want to cut into the sills, its too close to the subframe mounting points and jacking reinforcement. The skirts only sit about 1/2 inch lower than the sills, so nothing to be gained there.
I doubt much of that area is oringinal on the racecars, they have solid rear axle,5 linked, and air jacks, the whole platform of the body is modified.
