Hey guys, so today I put a stainless exhaust mani on my d13 single carb, I already had a decat pipe and stainless cat-back, but now I've lost all back pressure and the car is slow as hell :/ my problem is I can't turn the fuel screw on the carb as the engine management puts the fueling back to standard... Has anyone got any ideas if bigger jets would help? If so where would I look and also what size would I get as I don't know what standard ones are..[/quote]

Changing to a SS exhaust manifold shouldn't require an adjustment to the A/F ratio.
did you disconnect anything you didn't reconnect?
do you have an exhaust leak with is causing the lose of back pressure?
have you tried putting it back to the way it was before and see if it runs proper?

The reason I think it's losing all the back pressure is because it's a 1.3 and it now has no cat and roughly 2" pipes all through and it's running on a stand a/f ratio

Oh and by slow I mean I doubt it could reach 100mph right now
